BMW M2 Competition 3" Primary De-Cat Downpipe Performance Exhaust

F87 M2C S55 cat-delete front pipe for track and off road use

Free the twin-turbo S55 and let it breathe. This large-bore 76.2 mm straight-through front section replaces the factory primary converters on the M2 Competition, unleashing faster spool-up, sharper throttle response and a deeper, more purposeful tone. It bolts up to the standard non-OPF system for a clean, direct fit on pre-PPF cars only.

Ideal for enthusiasts chasing Stage 2 gains with ECU software, this cat delete turbo outlet pipe transforms the character of the car while opening headroom for power when paired with a remap. Our customers love the crisp response and aggressive soundtrack, and we have used this setup on customer builds with great results.

Why choose this cat delete down pipe
