Milltek Non-Resonated Cat-Back Exhaust - Audi MK3 TTS - Polished Tips - 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.
