Active Autowerke Equal Length Mid Pipe Non Resonated - F87 LCI M2 Comp

Unlock the sound your BMW M2 Competition should have had from factory. This equalised centre section for the F87 LCI M2C with the S55 engine transforms the tone from buzzy and raspy to a smooth, deeper straight-six note with a sharper motorsport edge. The non resonated, straight-through centre pipe increases volume and character while keeping refinement in the cabin compared with many louder alternatives.

Developed to correct the well-known pulse imbalance of the S55 twin-turbo setup, this clever centre exhaust adjusts the length on the passenger-side run and uses a patented sinusoidal crossover before an X-section to synchronise the pulses before they mix. The result is a richer, fuller soundtrack that removes the harsh “weed whacker” rasp and replaces it with a clean, even howl that builds beautifully to redline. You keep your choice of rear silencer or back box too, so it works brilliantly with the OE rear section or most aftermarket rear exhausts.

Why enthusiasts choose this centre section

• Refined straight-six character - equalised pulses for a smooth, mature tone
• Non-resonated straight-through design - more volume and presence without the tinny buzz
• Lighter than the factory centre - reduces weight compared with the OE mid section
• Improved response - helps turbo spool sooner with freer flowing pipework
• Keeps your current rear exhaust - compatible with stock and most performance back boxes
• Engineered for an exact fit on the F87 LCI M2C - precision-built for the S55 platform

Real-world benefits

• Smoother, deeper tone at idle and cruise with an addictive, high-quality roar under load
• Eliminates the uneven, pulsing “two three-cylinders” sound caused by unequal downpipe lengths
• Perfect pairing with stock or aftermarket rear sections for a tailored sound setup

Our experience

We have fitted and driven cars with this centre exhaust and the difference is immediate. Customers tell us it is the best-sounding M2C exhaust configuration they have tried, with the right balance of volume, character and refinement for road and track days.

Fitment notes

• Designed specifically for the BMW M2 Competition F87 LCI with the S55 engine
• Non-resonated version - ideal if you want more sound and a purer straight-through centre section
• Running decat or straight-through downpipes - we strongly recommend choosing the resonated option to control overall volume and harshness
