Description

The Genuine BMW G87 M2 CS M Performance Titanium Exhaust System is the factory-developed lightweight valved exhaust for the BMW G87 M2 CS, available as a complete replacement system for the CS or as a highly desirable retrofit upgrade for the standard G87 M2.

Originally developed specifically for the M2 CS, the system combines lightweight stainless-steel front pipes with a rear silencer manufactured entirely from titanium. BMW states that the M Performance system is over 30% lighter than the standard M2 CS exhaust, saving approximately 8kg, while delivering a more emotional interpretation of the S58 twin-turbocharged straight-six exhaust note.

For M2 CS owners, this package provides the Genuine BMW replacement system and associated components required when replacing the original M Performance titanium exhaust.

For standard G87 M2 owners, the same system can be retrofitted to bring one of the M2 CS's most desirable Genuine BMW components to the regular car. This is expected to be one of the most popular applications for the system, particularly for owners building their G87 using Genuine BMW M Performance and M2 CS parts rather than fitting a conventional aftermarket exhaust.

The system is available without tailpipes or with the flagship Genuine BMW M Performance carbon fibre and titanium tailpipes.

Two Applications: M2 CS Replacement or G87 M2 Retrofit

This system has two key applications across the G87 platform.

For the BMW G87 M2 CS, this is the Genuine BMW M Performance titanium exhaust originally developed for the vehicle. It can therefore be purchased as a replacement system for an M2 CS, whether replacing damaged components, refreshing the original exhaust or completing a vehicle that requires replacement exhaust hardware.

For the standard BMW G87 M2, the M2 CS exhaust can be retrofitted as an upgrade, bringing genuine CS titanium exhaust hardware to the regular car.

For many standard M2 owners, this retrofit is likely to be the main reason for purchasing the system. Rather than fitting an aftermarket exhaust, it provides the opportunity to upgrade using Genuine BMW hardware developed for the M2 CS.

Genuine BMW M2 CS Hardware

This isn't an aftermarket exhaust designed to replicate the M2 CS system. It is the Genuine BMW M Performance titanium exhaust developed for the G87 M2 CS.

That makes it equally relevant for two different applications: an M2 CS requiring the correct Genuine BMW replacement exhaust, or a standard G87 M2 being upgraded with authentic CS hardware.

The system combines:

  • Genuine BMW vehicle-specific development
  • Titanium rear silencer
  • Lightweight stainless-steel front pipes
  • Active exhaust valve functionality
  • Perforated internal pipework
  • Reduced weight
  • More distinctive S58 exhaust character
  • Optional Genuine BMW carbon fibre and titanium tailpipes

For owners who want to retain Genuine BMW components, it provides a factory-developed alternative to a conventional aftermarket exhaust system.

Over 30% Lighter Than the Standard M2 CS Exhaust

One of the biggest advantages of the M Performance system is its construction and resulting weight reduction.

BMW states that the silencer system is over 30% lighter than the standard component, representing a saving of approximately 8kg.

The system uses a carefully selected combination of materials:

Front Pipes: Lightweight stainless steel
Rear Silencer: Titanium

Rather than simply using titanium for visible cosmetic components, BMW manufactures the complete rear silencer from the lightweight material.

Titanium offers an excellent strength-to-weight ratio and is ideally suited to the high temperatures experienced within a performance exhaust system. For the M2 CS, where reducing unnecessary mass is an important part of the vehicle's specification, the approximately 8kg saving makes this a meaningful upgrade.

For standard G87 M2 owners retrofitting the CS system, the titanium construction is also one of its biggest attractions.

Full Titanium Rear Silencer

At the centre of the M Performance system is BMW's titanium rear silencer.

The complete rear silencer is manufactured from titanium and paired with lightweight stainless-steel front pipes, creating a mixed-material system developed specifically around the G87 platform.

Beyond the weight reduction, the titanium construction also gives the system a particularly special appearance underneath the car and differentiates it from the conventional exhaust fitted to the standard G87 M2.

For owners building a G87 using Genuine BMW CS components, the exhaust is one of the most substantial factory hardware upgrades available.

A More Emotional S58 Sound

Both the G87 M2 and M2 CS use BMW M's S58 3.0-litre twin-turbocharged straight-six, making the CS exhaust particularly appealing as a retrofit for the standard car.

BMW developed the M Performance system to amplify the characteristic six-cylinder twin-turbo sound, producing a more emotional exhaust note than the standard system.

The internal construction incorporates perforated inner pipes, helping create the M Performance exhaust's distinctive acoustic character.

Rather than simply pursuing maximum volume, BMW designed the exhaust to retain different sound characteristics depending on the vehicle's selected operating mode.

Active Valved Exhaust System

The M Performance exhaust uses an active valved configuration, allowing the exhaust character to vary depending on the vehicle settings.

On its intended M2 CS application, BMW describes the different characteristics as:

Sport & Sport+

These modes provide the system's most emotional and aggressive sound profile while remaining within applicable statutory requirements.

Efficient

Efficient mode retains greater refinement for everyday driving, while BMW states that the M Performance system still delivers a sportier and more emotional sound than the standard system.

When retrofitting the system to a non-CS G87 M2, functionality can depend on vehicle specification and installation. Professional installation by a BMW specialist familiar with the G87 platform is therefore strongly recommended.

Available With or Without Carbon Fibre & Titanium Tailpipes

The Genuine BMW M2 CS Titanium Exhaust is available from R44 Performance in two configurations:

Without Tailpipes

Ideal if you already have compatible Genuine BMW M Performance tailpipe trims or intend to source them separately.

With Carbon Fibre & Titanium Tailpipes

The complete configuration includes the Genuine BMW M Performance carbon fibre and titanium tailpipe trims, providing the exhaust with its distinctive finished appearance.

The carbon and titanium combination visually complements the titanium rear silencer and gives the rear of the M2 or M2 CS a far more distinctive appearance.

M Performance Carbon Fibre & Titanium Tailpipes

The optional Genuine BMW M Performance carbon fibre and titanium tailpipe trims provide the finishing touch to the system.

Their combination of exposed carbon fibre and titanium helps distinguish the M Performance system from the standard G87 exhaust and complements other carbon fibre components fitted to the M2 and M2 CS.

Genuine BMW uses separate left and right components:

Left Carbon/Titanium Tailpipe: 18305A291B7
Right Carbon/Titanium Tailpipe: 18305A291B8

BMW advises that titanium can naturally develop yellow or blue discolouration when subjected to increasing temperatures. This heat colouring is a natural characteristic of the material and should not be mistaken for a manufacturing defect.

Genuine BMW M2 CS Exhaust Part Numbers

The M Performance installation uses Genuine BMW components developed specifically for the G87 M2 CS.

Key part numbers include:

M Performance Titanium Silencer System: 18309505068

Left Front Pipe for Titanium Rear Silencer: 18305A6A741

What's Included?

Depending on the selected configuration, the package contains the components required for the M2 CS exhaust installation, including:

  • Genuine BMW M Performance exhaust system
  • Titanium rear silencer
  • Lightweight stainless-steel front pipes
  • Required clamping sleeves and/or fastening hardware
  • Carbon fibre and titanium tailpipe trims when selected

Choose from:

Exhaust System Without Tailpipes

or

Exhaust System With Carbon Fibre & Titanium Tailpipes

Tailpipe trims are required to complete the installation. If purchasing the version without tailpipes, compatible trims will need to be sourced separately.

An Ideal Genuine BMW Upgrade for the Standard G87 M2

For many customers, the biggest appeal of this system will be the ability to retrofit Genuine BMW M2 CS exhaust hardware to a standard G87 M2.

Rather than moving to a completely aftermarket exhaust system, this allows owners to upgrade their car using a component developed by BMW for the M2 CS.

Reasons to retrofit the CS exhaust to a standard G87 M2 include:

  • Genuine BMW M2 CS hardware
  • Titanium rear silencer
  • Lightweight stainless-steel front pipes
  • Reduced exhaust weight
  • More distinctive S58 exhaust character
  • Active valved design
  • Optional carbon fibre and titanium tailpipes
  • Ideal addition to a wider M2 CS-inspired build

For owners who prioritise Genuine BMW components, the M2 CS exhaust offers a particularly attractive factory upgrade.

Direct Replacement for the G87 M2 CS

For G87 M2 CS owners, this system also serves as the Genuine BMW replacement for the original M Performance titanium exhaust.

This makes it suitable when replacing an original exhaust system due to damage, wear or other servicing and repair requirements.

Using Genuine BMW components retains the intended titanium construction, valve functionality, fitment and appearance of the original M2 CS system.

Customers can also specify the carbon fibre and titanium tailpipes when replacements are required or when purchasing a complete system.

Installation & Retrofit Information

BMW quotes an approximate installation time of:

1.5 hours

for installation in its intended G87 M2 CS application.

BMW's specified procedures include:

AIR 18 12 031
Installation Instructions: 01295A49D74

Installation time and requirements may differ when retrofitting the system to a non-CS G87 M2.

Professional installation by a BMW specialist familiar with the G87 platform is strongly recommended. The installer should confirm all required mounting hardware, connections and valve functionality for the individual vehicle before installation.

Where applicable, the required licensing documentation should be retained in the vehicle.

Compatibility

Direct replacement for:

  • BMW G87 M2 CS

Retrofit application:

  • BMW G87 M2
  • BMW G87 M2 LCI

The system was originally developed by BMW for the G87 M2 CS and serves as the Genuine BMW replacement exhaust for that application.

It can also be retrofitted to non-CS G87 M2 models, making it a desirable upgrade for standard M2 owners looking to install Genuine BMW M2 CS titanium exhaust hardware.

For non-CS installations, professional installation is recommended and any additional retrofit requirements should be confirmed for the individual vehicle.

Why This Page Exists

R44 Performance sells parts that make cars faster, louder, sharper and better to drive. A good number of those parts change something a vehicle was originally certified with — the exhaust after the turbo, the catalytic converter, the particulate filter, the engine map, the intake, the suspension geometry, the lighting. That is the entire point of them. It is also the reason this page exists.

Whether a given part can lawfully be used on a public road depends almost entirely on where that road is. A downpipe that is a completely ordinary track-day part in one country is a criminal offence to fit to a road car in another. The same box, the same part number, two totally different legal answers. We ship worldwide, so we cannot write one rule that covers everybody — but we can be straight with you about it rather than burying a line of small print at the bottom of a checkout page.

So here is our position, in plain English:

  • Assume a performance part is off-road, track or competition use unless we have specifically told you otherwise. If a listing says "road legal", "E-marked", "ECE approved", "type approved" or quotes a CARB EO number, we mean it. If it says nothing, do not assume.
  • Ask us before you order, not after. Our team knows this catalogue extremely well and will happily tell you what a part does to a vehicle's emissions, noise and approval status. We would far rather spend ten minutes on an email than have you fail an inspection.
  • We will tell you when the honest answer is "don't". If a part is a bad idea for how you have described using the car, we will say so, and we will point you at something that is not.
  • We reserve the right to refuse or cancel an order where we believe a part is intended for unlawful use on a public road.

What we cannot do is tell you what is legal on your specific vehicle, in your specific town, under your specific inspection regime, or guarantee how an individual inspector or insurer will treat a modification. Those rules differ by country, by state or province, sometimes by city, and they change. That responsibility sits with you as the owner of the vehicle — and the summaries below are there to give you a running start on it.

Quick Guide By Market

Pick your market for a plain-English summary. These summaries are a starting point and a prompt to go and check properly — the full legal terms are further down this page, and they are what governs your purchase.

United Kingdom

In short: track and off-road use is not the problem. Fitting emissions or noise-affecting parts to a road-registered, MOT'd car is where UK owners get caught out.

  • The MOT test includes emissions checks and a visual inspection for emissions equipment. A car presented with a missing or defeated catalytic converter, DPF or GPF will fail, and the tester is required to record it.
  • Removing or defeating emissions control equipment on a road-going vehicle is an offence under the Road Vehicles (Construction and Use) Regulations 1986, quite separately from the MOT.
  • Replacement exhausts must not make the vehicle noisier than it was when it was type approved, and silencers on most modern cars are expected to carry the appropriate marking. Roadside enforcement and local-authority noise cameras do act on this.
  • Almost every modification — exhaust, remap, intake, suspension, wheels, aero — must be declared to your insurer. An undeclared modification can invalidate cover entirely, which is usually a far more expensive problem than the MOT.
  • Vehicles used only on private land, on track or in competition are outside the road traffic regime and can be built as you like.

What this means when you order from us: de-cat and decat downpipes, sports cats without approval, GPF/DPF delete pipes and the maps that go with them are supplied for off-road, track and competition use only. Non-emissions parts — most suspension, brakes, styling, cooling and interior products — are generally unaffected, but check anything that alters lighting or ride height.

Ireland & the EU / EEA

In short: broadly similar to the UK in principle, but several member states are considerably stricter in practice, and Germany is the strictest of all.

  • Periodic roadworthiness testing applies across the EU/EEA under national schemes — the NCT in Ireland, the Hauptuntersuchung (TÜV, DEKRA and others) in Germany, the contrôle technique in France, the APK in the Netherlands, and equivalents elsewhere. Emissions equipment is checked.
  • Tampering with emissions control equipment on a road vehicle is prohibited EU-wide, and several states treat it as a serious offence rather than a technicality.
  • Germany in particular: parts generally need their own approval — an ABE, an EC/ECE type approval, or a Teilegutachten followed by an inspection and entry into the vehicle's papers. Fitting an unapproved part can invalidate the vehicle's operating permit (Betriebserlaubnis) and, with it, your insurance. Do not assume a UK-market part is acceptable.
  • Since Brexit, orders shipped from the UK into the EU are imports. Duties, import VAT and customs clearance apply, and some carriers will hold emissions-related parts.
  • Track and motorsport use is, as in the UK, a separate matter and generally unrestricted.

What this means when you order from us: if you are in Germany, Austria or Switzerland, please talk to us before ordering exhaust, suspension or lighting parts so we can tell you what approval documentation, if any, exists for that product. For most other member states the UK guidance above is a reasonable guide, but your national test is the authority.

United States

In short: the strictest enforcement environment we ship into, and the one where you most need to know your own state's rules before you click buy.

  • Federal law — the Clean Air Act — prohibits removing or rendering inoperative any emissions control device on a road vehicle, and prohibits selling parts whose principal effect is to defeat one. The EPA has actively enforced this against tuners, installers and retailers in recent years.
  • California, and the states that have adopted California standards, additionally require aftermarket parts affecting emissions to hold a CARB Executive Order (EO) number to be legal for street use. No EO means off-road only, whatever the part does.
  • Inspection regimes vary enormously by state — some run OBD-II and visual checks annually, some by county, some not at all. A part that passes unnoticed in one state will fail in the next one over.
  • Race, competition and dedicated off-road vehicles are treated differently from street-registered vehicles, and that distinction is the one that matters.

What this means when you order from us: we do not represent any product as EPA-compliant or CARB-compliant unless the listing explicitly says so and quotes the EO number. Everything else is supplied for off-road, race and competition use only, and by ordering you are confirming that is how it will be used. Please check the EPA's guidance on aftermarket parts and tampering, and CARB's aftermarket parts database, before you order.

Canada

In short: federal emissions rules plus a patchwork of provincial equipment, noise and inspection rules.

  • Federal on-road vehicle emissions regulations under the Canadian Environmental Protection Act govern emissions control equipment on road vehicles.
  • Provinces set their own rules on inspections, equipment standards, exhaust noise and out-of-province vehicle admission — Ontario, British Columbia and Quebec each work differently.
  • Municipal noise by-laws are actively enforced in several major cities and are a common cause of tickets for loud exhausts.
  • Import duties, taxes and brokerage apply to orders shipped from the UK.

What this means when you order from us: treat emissions and exhaust parts as off-road and track use unless your province tells you otherwise. Check your provincial transport authority's equipment standards before fitting anything to a road car.

Australia & New Zealand

In short: modification rules are formalised and genuinely enforced, and both countries have a certification route for road-legal modifications.

  • Australia: vehicles must continue to meet the Australian Design Rules. National guidance on modifications sits in the Vehicle Standards Bulletin (VSB14), with each state and territory operating its own approval, engineering certification and defect-notice system. Emissions-related modifications are among the most tightly controlled categories.
  • State enforcement — defect notices, "canary" and "yellow sticker" stickers, and EPA-issued noise and emissions notices — is common in NSW, Victoria and Queensland in particular.
  • New Zealand: the Warrant of Fitness applies, and many modifications require Low Volume Vehicle (LVV) certification to remain road legal.
  • Motorsport, club-level competition and off-road vehicles operate under separate rules.

What this means when you order from us: if you intend a part for road use, please check with a certifier or your state authority first — the certification route exists and works, but it needs to be planned before you buy, not afterwards. Otherwise, parts are supplied for track and competition use.

Rest of the world

In short: we ship almost everywhere, and almost everywhere has its own inspection and approval regime.

  • Japan operates the shaken inspection, with noise and emissions standards that replacement exhausts must be certified against.
  • The Gulf states, Singapore, South Africa and most of Asia run periodic inspection or registration checks covering exhaust, emissions, lighting and glazing.
  • Many countries restrict the import of emissions-defeating parts at the border, and customs may hold or seize them regardless of what we have written on the paperwork. We will not mis-declare goods to get around this.
  • Import duties, taxes and clearance charges are the customer's responsibility in all territories.

What this means when you order from us: please check your national vehicle inspection authority's rules before ordering, and ask us if you are unsure what a part actually changes. See our International Shipping Terms & Conditions for the shipping side of things.

Still not sure? Send us a message with your vehicle, where it is registered and how you use it, and we will give you a straight answer before you spend anything.

The Full Disclaimer

Many of the products sold on r44performance.com are designed and intended exclusively for off-road, track, competition and race use. By purchasing any performance or aftermarket part from R44 Performance, you agree and acknowledge that such products will only be used for off-road, track or competition purposes, and will not be fitted to a road-registered vehicle in any manner that breaches the laws of the country in which that vehicle is used.

1. Off-Road, Track & Competition Use Only

Products that fall under this disclaimer include, but are not limited to:

  • Exhaust systems and exhaust components — downpipes, midpipes, cat-back and turbo-back systems, headers/manifolds, valved and non-valved systems
  • Catalytic converter replacements, sports cats, de-cat pipes and decat downpipes
  • GPF/OPF and DPF delete or replacement pipes
  • Cold air intakes, induction kits and intake systems
  • ECU remaps, tuning software, piggyback modules and performance tunes
  • Turbocharger, supercharger and forced-induction upgrades
  • EGR delete kits, secondary-air and other emissions-related components
  • Suspension, brake, lighting, aerodynamic and bodywork parts that may not hold road type approval in your territory
  • Any other performance part that may alter a vehicle's factory emissions, exhaust, noise or safety configuration

Important: a product does not need to be explicitly labelled "off-road use only", "for race use only", "not road legal", "track use only" or "non-EPA compliant" in its description for this disclaimer to apply. This disclaimer applies to all products sold on r44performance.com that fall within the categories above, whether or not the individual product listing carries a specific compliance notice. Some listings do carry such notices; the absence of one does not imply that a product is road legal, type approved or emissions compliant in your territory.

2. UK & EU Road Legality

R44 Performance is based in the United Kingdom. Many aftermarket performance parts we supply may not comply with the Road Vehicles (Construction and Use) Regulations 1986, UK or EC/UNECE type approval requirements, MOT testing requirements, or national and local noise and emissions standards in the UK, the European Union or any other territory.

Under UK law it is, in general, an offence to use a vehicle on a public road if a component required for emissions control has been removed, disabled or rendered less effective, or if the vehicle no longer meets the noise or construction standards it was type approved to. Vehicles presented for an MOT with a missing or tampered catalytic converter, DPF or GPF will fail the test.

It is your sole responsibility to:

  • Understand the road traffic, type approval, noise and emissions laws that apply where the vehicle is registered and used, before placing an order
  • Determine whether a product may lawfully be fitted to your vehicle for the use you intend
  • Check whether a part carries the E-mark, type approval or homologation required in your territory, where such approval is required
  • Declare all modifications to your motor insurer, and satisfy yourself that your cover remains valid
  • Understand that fitting a non-compliant part to a road-going vehicle may result in an MOT failure, a roadworthiness prohibition, fines, penalty points, prosecution or vehicle seizure

Unless a listing expressly states otherwise (for example "road legal", "E-marked", "ECE approved" or "type approved"), R44 Performance makes no representation that a product is road legal, type approved or emissions compliant in the UK, the EU, or any other territory.

3. United States — EPA, Clean Air Act & CARB

Many aftermarket performance parts sold on this website do not comply with United States Environmental Protection Agency (EPA) regulations, the Clean Air Act, or state-level emissions standards, including but not limited to California Air Resources Board (CARB) requirements.

If you are ordering from, or shipping to, the United States, it is your sole responsibility to:

  • Research and understand all applicable federal, state and local emissions laws in your jurisdiction before placing an order
  • Determine whether a product is legal for your intended use in your state before purchasing
  • Verify whether a product is CARB-exempt or CARB-compliant where your state requires it — California residents especially
  • Understand that installing non-compliant parts on a street-driven vehicle may result in failed emissions inspections, fines, citations, vehicle impoundment or other legal consequences

R44 Performance does not guarantee that any product complies with emissions law in your state or jurisdiction unless the product listing expressly states otherwise (for example "CARB EO number issued" or "50-state legal"). Parts sold by R44 Performance are not offered or represented as EPA-compliant emissions-related replacement parts for road use in the United States.

4. Shipping & Export Restrictions

R44 Performance does not knowingly ship emissions-defeating or off-road-only parts to countries, states or jurisdictions in which such products are unlawful, unless the customer confirms that the product is being purchased exclusively for race car, track or off-road vehicle use.

By completing a purchase, you represent and warrant that any off-road or non-compliant product will be used solely for lawful off-road, track or competition purposes. We reserve the right to refuse, cancel or refund any order at our discretion where we believe a product is intended for unlawful use, and to require written confirmation of intended use before an order is dispatched. We will not mis-describe or under-declare goods on customs paperwork under any circumstances.

You are also responsible for any import duties, taxes, customs clearance requirements and import restrictions that apply in the destination country. Please also read our International Shipping Terms & Conditions and our Shipping Policy.

5. Vehicle Warranty Disclaimer

Fitting aftermarket performance parts may affect or void all or part of your vehicle's manufacturer warranty, extended warranty or approved-used warranty.

In the UK and EU, block exemption rules mean a manufacturer cannot automatically void an entire warranty simply because an aftermarket part has been fitted; however, a manufacturer or dealer may refuse a claim where it believes the part contributed to the failure. In the United States, the Magnuson-Moss Warranty Act provides comparable protections, but individual dealers and manufacturers interpret warranty coverage differently.

R44 Performance is not responsible or liable for any warranty claim refused or reduced by a vehicle manufacturer, dealer or warranty provider as a result of parts purchased from us being fitted. This includes, without limitation, engine, powertrain, drivetrain, emissions system and any related warranty coverage. Our own product warranty position is set out in our Warranty Policy.

6. Professional Installation

All performance and aftermarket parts should be fitted by a qualified professional technician or a competent specialist workshop, using the correct tools, torque figures and procedures. Improper installation can cause vehicle damage, component failure, fire risk, safety hazards or a voided warranty.

Fitting guides, torque figures and instructional content published by R44 Performance are provided for general guidance only and do not replace manufacturer instructions or professional judgement. R44 Performance is not liable for any damage, injury, loss or issue resulting from incorrect, incomplete or unsuitable installation, or from installation carried out by the customer or by a third party.

7. Assumption of Risk & Waiver of Liability

By purchasing performance or aftermarket parts from R44 Performance, you acknowledge, agree and represent that:

  • The product may be intended for off-road, track, race or competition use only
  • You will use off-road products only for lawful off-road, track or competition purposes, and will not use them on public roads in breach of applicable law
  • You are solely responsible for determining the legality of purchasing, fitting and using the product in your jurisdiction
  • You assume all risk associated with the purchase, installation and use of aftermarket parts, including use on track, at competitive events and in motorsport
  • To the fullest extent permitted by law, R44 Performance shall not be liable for any fine, penalty, citation, failed test or inspection, roadworthiness prohibition, vehicle seizure, prosecution, legal cost, vehicle damage, engine or component failure, personal injury, or any other loss or damage arising from the purchase, installation or use of products bought from this website

  • You have read and agree to this disclaimer as part of our Terms of Business

Your statutory rights. Nothing in this disclaimer excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded. Nothing here affects the statutory rights of consumers under the Consumer Rights Act 2015 or equivalent legislation in your country in respect of goods that are faulty, not as described or not of satisfactory quality.

8. No Returns or Cancellations for Compliance Reasons

R44 Performance does not accept returns, exchanges or cancellations on the basis that a customer has discovered after ordering that a product is not road legal in their country or state, will not pass an MOT or emissions inspection, is not type approved, is not CARB-compliant, or otherwise does not meet a local regulatory requirement — unless the product listing expressly stated that it was compliant and it is not.

It is your responsibility to verify all compliance requirements before purchasing, and we would much rather you asked us first. Please review our Returns & Refunds Policy for full details of when a return or cancellation can be accepted, including your statutory cancellation rights where these apply.

9. Product Descriptions & Listings

While we work hard to provide accurate product descriptions, fitment data and specifications, R44 Performance does not guarantee that every listing carries complete emissions or compliance information. Manufacturers also change specifications, approvals and part content without notice.

The absence of an off-road or compliance notice in a product description does not imply that a product is road legal, type approved or emissions compliant. If you are unsure whether a product may lawfully be used in your area, please contact us before ordering and we will do our best to help.

10. Agreement

This disclaimer is incorporated into and forms part of our Terms of Business. Continued use of this website and the completion of any order constitutes acceptance of these terms.

This page is provided for general information and does not constitute legal advice. Regulations differ by country, state and region and change over time.
