Upgrade the sound and response of your BMW M2 Competition F87 LCI S55 with the Active Autowerke Equal Length Mid Pipe also known as the EL Midpipe. This direct fit exhaust centre section is engineered to fix the infamous S55 rasp and deliver the smooth deep motorsport inspired inline six tone enthusiasts want from a performance BMW. Available in resonated or non resonated versions this M2C mid pipe upgrade transforms everyday drivability and wide open throttle character while keeping fitment simple and reliable.
Developed through extensive R and D and proven on road and track Active Autowerke uses a patent pending sinusoidal crossover to equalise runner length before the X pipe merge. By correcting the unequal length pulses created by the factory downpipes the EL midpipe dramatically reduces high pitched rasp and restores the rich full bodied six cylinder sound. It is lighter than the factory centre section and promotes quicker turbo spool and sharper throttle response for noticeable gains in the low to mid range.

Why choose an Equal Length Mid Pipe for the S55
The S55 twin turbo layout creates a length difference between the front and rear downpipes. When these uneven pulses mix in a standard crossover or X pipe they can produce the well known weed eater rasp. Active Autowerke solves this by equalising the pipe lengths before the merge using a patent pending sinusoidal crossover design. The result is a smoother deeper clearer soundtrack under load with the classic inline six character you expect from a BMW M car.
