Milltek 80mm Resonator Bypass - BMW F2X M140i M240i - Fits M Performance Rear Silencer - SSXBM1433

Milltek 80mm Resonator Bypass for the BMW M240i and M140i (F2X), Fits M Performance Rear Silencer

The B58 in the M240i and M140i is held back by two factory resonators that smother its note. This Milltek 80mm mid-pipe replaces both with straight mandrel-bent T304L stainless, sharpening the six-cylinder sound and freeing up flow while keeping the optional BMW M Performance rear silencer in place.

• Double Resonator Delete: removes both factory resonators for a sharper, louder note.
• Improved Flow: 3.15in (80.00mm) mandrel-bent T304L stainless front pipe and axle pipe.
• Fits the M Performance Rear Silencer: supplied with the correct adapter.
