Active Autowerke BMW M2 Competition F87 Single Midpipe

This is one of the most popular modifications available for the S55, and for good reason. The factory exhaust on the M2 Competition uses a dual-pipe design that restricts exhaust flow and produces an unnaturally flat, almost "lawnmower-like" drone rather than a proper M-series growl. Active Autowerke's 3.5in Single Midpipe solves both problems at once, improving flow, delivering a deeper, more throaty tone, and letting the turbos spool more quickly.

The pipe is engineered specifically around the F87 M2 chassis for a precise fit with no ground clearance issues. Built from 304 stainless steel with an oval profile section, it combines maximum flow efficiency with genuine durability and a perfect factory-matching fit. On the dyno, this single midpipe shows real, measurable gains, +18hp and +40Nm over stock, with noticeably sharper response through the low and mid rev range, and an exhaust note that finally sounds like a proper BMW M car should.

Works with: Factory mounting points. Plug-and-play installation with no permanent modification required.
