Fabspeed's Muffler Bypass Exhaust System deletes the restrictive rear muffler on the F22 M235i, shedding 14 lbs and letting the N55 engine's voice come through. Expect an intoxicating, menacing barrage of pops and crackles on deceleration; in-cabin tone stays reasonable, and Fabspeed says it's still comfortable as a daily driver even paired with their Sport Cat Downpipe. It's built to fit both the standard rear bumper and the M Performance rear diffuser. Built from 14-16 gauge T304L stainless steel piping, it includes tips in your choice of finish. Installation requires cutting the factory exhaust at a marked breakpoint; the kit installs over the factory piping with an included Torca clamp, and the factory muffler can be reinstalled later.

What does the Resonator Bypass Midpipe option add?

It's an add-on for an even louder, more aggressive exhaust setup on top of the Muffler Bypass system.

Which option should I choose?

Choose the options that match your actual car, not preference: drivetrain (RWD or AWD) and diffuser type (standard M235i or M Performance) need to match your bumper setup for proper fitment. The midpipe option is genuinely optional — add the Resonator Bypass Midpipe for the loudest, most aggressive setup, or skip it to keep the standard muffler-bypass sound. Tip finish (polished stainless steel, satin black, or carbon fiber) is a styling choice on top.

Who installs it?
