Active Autowerke BMW G87 M2 Valved Axle Back Exhaust System

Unlock a deeper, more characterful exhaust note from your BMW G87 M2 with the Active Autowerke Valved Axle Back Exhaust System. Developed specifically for the S58-powered M2, this premium rear exhaust replaces the restrictive-sounding factory rear section with a freer-flowing 304 stainless steel valved system, delivering greater volume and a deeper, throatier tone while retaining BMW's factory exhaust valve functionality.

While the G87 M2's 3.0-litre twin-turbocharged S58 straight-six delivers exceptional performance, its factory exhaust system can leave some enthusiasts wanting considerably more sound. Active Autowerke developed its G87 exhaust range to address exactly that, creating a system that brings more of the S58's character into the driving experience without simply chasing maximum volume.

The axle-back system reuses the original BMW exhaust valve actuators, allowing the vehicle to retain factory valve operation. The result is a more engaging exhaust note combined with the flexibility expected from a modern BMW M car.

For an even greater transformation, the Active Autowerke rear exhaust can be paired with the brand's Equal Length X-Pipe or Single Midpipe and GESI catted downpipes to create a complete G87 M2 exhaust package.

How Does the Active Autowerke G87 M2 Exhaust Sound?

Active Autowerke designed this axle-back specifically to address the relatively subdued character of the factory BMW G87 M2 exhaust system.

Rather than simply creating maximum volume, the focus is on producing a lower, deeper and throatier exhaust note that better represents the performance of the S58-powered M2.

The rear exhaust increases sound compared with the standard rear silencer while optimising exhaust flow and resonance. Crucially, it retains the factory valved functionality, allowing the exhaust system to continue responding to the BMW's original valve controls.

For owners looking for a noticeable but relatively subtle improvement while retaining the factory midpipe, the axle-back can be installed as a standalone upgrade.

Factory Exhaust Valve Control

One of the key advantages of the Active Autowerke G87 M2 axle-back is its ability to retain the factory BMW exhaust valve actuators.

Rather than introducing a separate aftermarket valve controller or remote system, the Active Autowerke exhaust is engineered to reuse the original BMW actuators.

This retains the integrated functionality of the factory exhaust valve system while allowing you to benefit from the deeper tone of the upgraded rear section.

For a modern performance car like the G87 M2, this provides an excellent balance between additional exhaust character and everyday usability.

Factory Midpipe vs Upgraded Midpipe

The Active Autowerke G87 M2 Valved Axle Back can be configured for owners retaining their original BMW midpipe as well as those building a more comprehensive Active Autowerke exhaust system.

It is important to choose the correct configuration when ordering.

If you initially purchase the version designed to connect to the factory BMW midpipe and later upgrade to an Active Autowerke or other aftermarket midpipe, different connecting pipes will be required and will involve an additional cost.

It's therefore worth considering your future exhaust plans before selecting your configuration.

Want a Bigger Change in S58 Sound?

While the Active Autowerke axle-back improves the tone and volume of the factory exhaust, the biggest change in the G87 M2's exhaust character comes from replacing the factory midpipe.

For owners wanting a more dramatic transformation, Active Autowerke offers its G87 M2 exhaust system as a modular package consisting of:

• Active Autowerke Valved Axle Back Exhaust
• Active Autowerke Equal Length X-Pipe or Single Midpipe
• Active Autowerke GESI Catted Downpipes

Combining the axle-back with an upgraded midpipe significantly changes the S58's tone and character compared with replacing the rear section alone.

If you're primarily looking for a deeper, more refined enhancement while keeping the rest of the exhaust standard, the axle-back remains an excellent standalone upgrade.

304 Stainless Steel Construction

The Active Autowerke G87 M2 axle-back is manufactured from 304 stainless steel, providing excellent strength, corrosion resistance and durability for long-term road use.

Active Autowerke has more than four decades of experience developing BMW performance products, and the G87 system continues its focus on combining performance with refinement and manufacturing quality.

The system is proudly made in the USA and engineered specifically around the latest-generation M2 rather than being adapted from a universal exhaust design.

Tested & Guaranteed G87 M2 Fitment

Fitment is a major focus of Active Autowerke's quality-control process.

Every G87 M2 rear exhaust section is individually test-fitted using Active Autowerke's in-house G87 exhaust fixture before being approved for sale. This allows the company to verify positioning and fitment before each system leaves its facility.

Active Autowerke guarantees precise fitment across the BMW G87 M2 application.

All necessary installation hardware is supplied with the system.
