Milltek Non-Resonated Cat-Back - Audi TT MK1 - Polished Tips - SSXAU1042

The Milltek Non-Resonated Cat-Back Exhaust System is engineered for the Audi TT MK1 V6 Quattro, providing direct factory fitment with no modification required. This 2.76" (70mm) mandrel-bent T304L stainless steel system replaces the OEM cat-back exhaust entirely, optimizing flow and acoustic character.

Constructed from hand-finished T304L stainless steel, this non-resonated design eliminates the factory resonance chamber to deliver a more pronounced, aggressive tone at full throttle while maintaining OEM hanger compatibility. The large-bore 2.76" diameter facilitates improved exhaust scavenging and measurable horsepower gains over stock.
