Cobra Sport BMW M2 Competition F87 S55 3"/76.2mm Primary De-Cat/Decat Catless Cat Delete Downpipe Front Pipe (Turbo Outlet) T304 Stainless Race Pre-OPF/PPF/GPF | M2C Exhaust Upgrade for Stage 2

Unlock serious performance and sound from your F87 M2 Competition with this 3 inch cat delete turbo outlet front pipe. Designed for the S55 twin turbo engine, this catless primary section slashes back pressure for faster spool, crisper throttle response and a richer, more aggressive soundtrack.

Manufactured in the UK by Cobra Sport from premium T304 stainless steel with CNC mandrel bends and precision TIG welds, this race downpipe replaces the factory primary catalytic converters on pre-PPF cars. The free-flowing 76.2 mm bore transforms drivability and pairs perfectly with a Stage 2 calibration for meaningful power gains.

We have fitted this setup to customer M2C builds and the feedback has been outstanding. Expect a deeper tone, improved turbo response and that authentic motorsport feel enthusiasts want from a proper cat delete front section.
