Active Autowerke AA Mid Pipe for BMW M2 Competition (M2C) & M2 CS F87 S55 - Single 3.5in Exhaust Centre Section, OPF Delete, Rasp Fix (2016+)

Active Autowerke AA Centre Section for F87 M2C and M2 CS

Give your F87 S55 the soundtrack and response it deserves with the Active Autowerke single 3.5 inch oval centre section. This precision built mid section replaces the restrictive factory dual pipe arrangement to smooth out the harsh strimmer-like buzz, reduce back pressure and bring out a deeper, more mechanical tone that suits an M car. Developed by a BMW tuning specialist with decades of experience, it is a direct replacement centre pipe for the M2 Competition and M2 CS that delivers real world gains and excellent driveability.

If you are hunting for a rasp reduction solution, a GPF or OPF removal pipe, a single oval link pipe, a centre pipe upgrade or a performance exhaust middle section for the F87 platform, this AA unit is the proven choice. We have installed this on our own builds and on customer cars and feedback has been consistently positive for sound quality, spool and overall refinement.

Highlights

• Single tube layout cancels the uneven turbo pulse noise from the stock dual mid section for a richer, more cohesive note
• Large 3.5 inch oval profile improves flow while maintaining ground clearance for daily use and track work
• Less restrictive than the factory pipework with small crossover and resonators
• Audibly deeper tone with reduced rasp and more presence under load
• Designed specifically for the F87 chassis with the S55 twin turbo straight six

Performance benefits

• Up to 18+ whp over stock*
• Up to 30+ lb ft over stock*
• Lower back pressure and quicker turbo response
• Stronger low and mid range punch
• Lighter than the OEM mid section

The transformation is immediate. Expect a cleaner, more mature exhaust character with improved throttle response. Customers regularly comment that it removes the tinny buzz and replaces it with a proper M car growl without sacrificing drivability.
