Description

The CTS Turbo 3" Stainless Steel High-Flow Catted Downpipe is designed for BMW S55 engines found in M3, M4, and M2 Competition models. Constructed from durable 304 food-grade stainless steel, this downpipe features a large 3-inch diameter for improved exhaust flow and performance.

It is engineered with factory-like O2 sensor placement for seamless integration and is compatible with both factory and aftermarket mid-pipes. The downpipe utilizes CAD simulation for optimal flow routing and is designed using 3D scanning technology to ensure a perfect fit. Users can expect enhanced spool, better transient boost response, higher boost levels, and an aggressive exhaust sound.
