Milltek 80mm Resonator Bypass - BMW F2X M140i M240i - Fits OE Rear Silencer - SSXBM1432

Milltek 80mm Resonator Bypass for the BMW M240i and M140i (F2X), Fits OE 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 factory 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 OE Rear Silencer: supplied with the correct adapter.
• Installation: the OE system must be cut to fit.
