The Milltek Non-Resonated Cat-Back Exhaust System is engineered for the Audi MK3 TTRS Quattro, delivering direct factory fitment and a heightened exhaust character. This 3.00" (76.20mm) mandrel-bent system replaces the OEM cat-back section with no modification required. Hand-finished T304L stainless steel construction ensures longevity and corrosion resistance. The non-resonated design eliminates the OE resonance chamber, producing a more pronounced full-throttle note while maintaining street-legal compliance. Cerakote Black oval trim tips provide a premium visual finish. Direct OEM hanger compatibility and precise CNC engineering ensure seamless installation. Fitment • Audi TTRS MK3 Quattro (all model years) • Cat-back system (turbo and downpipe remain OEM) • Direct factory fitment - no welding or modifications Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
