Description
CTS Turbo is proud to announce the release of our BMW S58 G80/G82/G87 M2/M3/ M3 Competition/M4/M4 Competition High-Flow CATS.
Our stainless steel downpipes allow for faster spool, better transient boost response, higher boost, and great sound. Our High-Flow CATS are the first part of our modular exhaust system and are compatible with factory mid-pipes. You should expect strong torque gains when paired with appropriate tuning software. We used CAD simulation to streamline the flow of exhaust gasses and ensure seamless integration with the factory and CTS exhaust components. Many hours of R&D were spent to ensure a perfect fit, smooth exhaust flow, and excellent sound.
Use of Bootmod3 software compatible and is strongly recommended. CEL will illuminate if correct software tuning is not used.

- Durable 304 food-grade stainless steel, 3″ or 76mm diameter
