F87 M2C S55 Catted Downpipes

Upgrade your S55-powered M2 Competition with a high-flow 200-cell catalytic converter downpipe engineered for improved exhaust velocity, reduced backpressure, and sharper turbo response. Constructed from T-304/SS304 stainless steel with CNC-machined flanges and mandrel-bent piping, this setup is designed for precise fitment, durability, and consistent performance under heat load.

The 200-cell catalyst offers a strong balance between flow and emissions control, delivering a more aggressive exhaust note and supporting higher performance calibration while retaining a streetable catted configuration. Bolt-on installation makes it compatible with OEM and aftermarket exhaust systems.
