The Milltek Resonated Cat-Back Exhaust System is engineered for direct factory fitment on the Audi MK3 TTS.

Hand-finished T304L stainless steel construction ensures durability and corrosion resistance. The resonated design fine-tunes the OE resonance point to eliminate drone while preserving a more pronounced, sportier exhaust note at full throttle. Polished oval tips complete the OEM+ aesthetic. Uses original hangers for seamless installation. Fitment • Audi MK3 TTS (8S chassis) • Direct cat-back replacement • No modification required • OEM hanger compatible Designed and manufactured in the UK with 40+ years of performance exhaust heritage.
