Fabspeed BMW M240i (F22) Muffler Bypass Exhaust System (2016+)

The factory M240i rear muffler is a heavy, log-shaped can that keeps the B58 quiet. Fabspeed's muffler bypass removes it, which cuts weight and lets the engine sound the way a sports car should. You hear the pops and crackles already built into the BMW calibration, plus a throaty growl when you accelerate.

What you get

• Replaces the factory rear muffler with a lighter bypass section.
• More sound, including the stock overrun pops and a deeper growl under throttle.
• No interior drone, per Fabspeed.
• Emissions-legal, since it changes only the muffler section.

Tip finish

Choose Satin Black, Carbon Fiber or Polished tips when you order.
