DESCRIPTION
Want your AMG to sound like a proper V8 should?
WSTN Performance Catless Downpipes for the Mercedes-Benz C63 and C63S AMG (W205, Sedan, Coupe and Wagon) replace the factory catalytic converters with a high-flow, unrestricted setup. Engineered from premium T304 stainless steel and wrapped in an OEM-style thermal shield, these pipes unleash raw turbo sound, reduce spool time, and drop engine bay temps, all while keeping daily drivability intact.
Why Upgrade?
✅ No restrictions – Fully catless for maximum flow and response
✅ Built to handle heat – stainless steel with OEM-style heat shielding
✅ More power, faster spool – Reduces backpressure for better throttle and turbo response
✅ Mandrel-bent piping – Smooth transitions ensure optimal flow and performance
✅ Precision-built – CNC flanges and leak-free fitment
✅ Bolt-on installation – No cutting or welding required
✅ Trusted manufacturing – Made in the same facilities as top global brands
✅ 1-Year Warranty – Peace of mind backed by performance
