Genuine BMW G87 M2 CS M Performance Titanium Exhaust System

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.

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.
