Cat-Back Exhaust
Brand: Milltek
Part #: SSXAU575
SKU: MK-SSXAU575
The Milltek Non-Resonated Cat-Back Exhaust System is engineered for the Audi MK3 TTS, replacing the factory exhaust with a direct-fit 3.00" (76.20mm) mandrel-bent T304L stainless steel system. This configuration delivers enhanced exhaust flow, measurable performance gains, and a distinctly aggressive sound character without resonance chambers. Hand-finished T304L stainless steel construction with polished oval tips ensures durability and premium aesthetics. The non-resonated design eliminates OE resonance points for a full-throttle tone engineered specifically for the MK3 platform. Uses OEM hangers and mounting points-no modification required. Suitable for track use and closed-course driving; street legality varies by jurisdiction. Fitment • Audi TTS MK3 (8S) all engine variants • Cat-back configuration (factory cat remains) • Direct factory fitment, OEM+ installation Every system is developed in-house, dyno-tested, and built to precise specifications-not universal-fit alternatives. This exhaust reflects Milltek's commitment to engineered tone and measurable performance over marketing claims. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
