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.

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
• To the fullest extent permitted by law, you waive any claim, demand or cause of action against R44 Performance, its directors, employees and agents relating to emissions compliance, type approval, road legality, off-road use, or any legal consequence arising from the use of products purchased on r44performance.com
• 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

By completing a purchase on r44performance.com, you confirm that you have read, understood and agree to this Off-Road & EPA Disclaimer in its entirety. 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. If you are in any doubt about the legality of a modification, seek advice from your local licensing or enforcement authority, or from a qualified professional, before purchasing.
