The Milltek Resonated Cat-Back Exhaust System is a direct factory fitment for the Audi MK1 TT (all variants including V6 Quattro). This 2.76" (70mm) mandrel-bent T304L stainless steel system replaces the factory cat-back and uses OEM hangers for hassle-free installation with zero modification required. Hand-finished T304L stainless construction delivers corrosion resistance and a refined appearance. The resonated design targets the OE resonance point to eliminate drone while maintaining a sportier, more pronounced tone at full throttle. Decibel-tested for balanced acoustic character-more engaging than stock, but engineered for street use without excessive harshness.
