Active Autowerke | BMW F87 M2 Competition Equal Length Midpipe

Transform the sound and performance of your BMW M2 Competition (F87) with the Active Autowerke Equal Length Mid Pipe. Engineered with over 39 years of BMW performance expertise, this patented exhaust solution (US Patent 11248511, UK/EU patent pending) corrects the uneven exhaust pulse of the S55 engine, delivering the deep, refined, and aggressive tone the M2C deserves.

The stock M2 Competition exhaust often produces a high-pitched “raspy” note due to unequal downpipe lengths, making the S55 sound like two mismatched inline-3 engines. Active Autowerke’s innovative sinusoidal crossover design equalizes exhaust pipe lengths before merging, eliminating the “weed eater” tone and producing the smooth, throaty roar true to a BMW inline-6.

Unlike other systems that require a full rear section replacement, this mid pipe is a direct-fit solution that works seamlessly with factory and aftermarket exhausts—no compromises needed.

⚠ Note: If your M2 Competition runs catless downpipes, we strongly recommend the resonated version of this mid pipe for the best sound quality.

Key Features:

• Designed specifically for the BMW M2 Competition F87 (S55 engine)

• Equal length design eliminates S55 exhaust imbalance

• Lighter than the OEM mid pipe system

• Faster turbo spool and sharper throttle response

• Gains in low-end and mid-range power

• Direct bolt-on fitment, compatible with stock and aftermarket rear exhaust systems

Applications:

• BMW M2 Competition F87 (2019–2021, S55 engine)

Upgrade your BMW M2 Competition with the Active Autowerke Equal Length Mid Pipe and unleash the balanced, aggressive exhaust note the S55 engine was meant to deliver.
