DESCRIPTION
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
