Overview
The Milltek Resonated Cat-Back Exhaust System is engineered as a direct factory replacement for the Audi TT MK1 V6 Quattro. This mandrel-bent T304L stainless steel system delivers OEM+ fitment without modification, pairing improved exhaust flow with a refined sound character tuned to the resonance characteristics of the original platform.
Constructed from T304L stainless steel and hand-finished to Milltek standards, the 2.76" (70mm) bore provides measurable flow gains over factory setup. The resonated design eliminates drone at cruise while maintaining a sportier full-throttle note. Direct OEM hanger compatibility and slip-fit connections ensure installation requires no cutting, welding, or bracket fabrication.
