High-Flow Sport Catalyst Front Pipe for BMW N20 2.0 Turbo Engines

Give your F-series 2.0 petrol turbo the breathing room it deserves with this high-flow sport catalyst front section from Wagner. Built from 1.4301 stainless steel 304 and engineered for an exact bolt-on fit, it relieves exhaust restriction, reduces thermal load on the turbo and delivers crisper boost response with noticeably stronger mid-range pull. The 200 cpsi Euro 6 coated catalyst combines excellent flow with robust durability, all while retaining OEM-style fitment points for a clean, hassle-free install.

Why enthusiasts choose it

• 1.4301 stainless steel 304 construction for longevity and corrosion resistance
• 200 cpsi Euro 6 coated sport catalyst for high flow and reliability
• Lower back pressure for faster spool, improved throttle response and more usable torque
• Reduced heat stress on the turbocharger for improved component life
• Plug-and-play replacement that uses factory mounting locations
• Connection diameter 105 mm
• Manufactured by Wagner in Germany

We run this part on our own builds and have fitted it to many customer cars. Feedback is consistently positive on fit quality, smoother turbo response and the punchier mid-range that comes from improved flow.
