CTS Turbo 2015-2020 BMW M3/M4/M2 C (F8X) 3″ Stainless Steel Downpipes w/ High-Flow Cats

DESCRIPTION

Our stainless steel high-flow CAT downpipes allow for faster spool, better transient boost response, higher boost, and great sound.  Our downpipes are the first part of our modular exhaust system and are compatible with factory mid-pipes and our upcoming CTS Turbo 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.

• Large 3″

• Factory-like placement of O2 sensors
• Designed using the latest 3D scanning technology
