WSTN BMW S55 M3/M4/M2 Competition Catless Downpipes (/F80/F82/F83/F87)

Want your car to sound as good as it looks?

WSTN Performance Catless Downpipes replace the restrictive factory catalytic sections with a high-flow catless system. Built from premium stainless steel and wrapped in an integrated thermal-shield exterior, these pipes deliver faster turbo response, lower engine-bay temps, and a sharper, more aggressive exhaust note, without sacrificing daily drivability.

Why Upgrade?

✅ High-flow design reduces backpressure, unlocks performance and tunabilty

✅ T304 stainless steel construction for superior heat and corrosion resistance

✅ OEM-style heat-shield wrap reduces radiant heat and improves engine bay temps

✅ Mandrel-bent piping ensures smooth airflow and maximum efficiency

✅ CNC-machined flanges & TIG welds for perfect fitment and leak-free sealing

✅ Direct bolt-on (no cutting, no welding) when matched to the correct model

✅ Manufactured in the same facilities as premium global brands

✅ 1-Year Warranty for total peace of mind
