The Milltek 80MM Race Non-Resonated Cat-Back Exhaust System is engineered specifically for the Audi 8V RS3 (2017+). This direct factory fitment replaces the OEM silencer with a race-spec design, delivering maximum volume and flow with zero resonance tuning. Pipe diameter: 80mm (3.15"). Uses OEM hangers and mounting points - no modification required. Constructed from T304L stainless steel with hand-finished burnt titanium trim tips. The non-resonated design eliminates the factory resonance chamber, targeting full-throttle character with no sound-deadening compromise. Race Spec Rear Silencer reduces system weight while preserving the aggressive acoustic profile at cruise and full load. Mandrel-bent throughout for consistent bore and optimized scavenging. • Fitment: Audi 8V RS3 (2017+) • System Type: Cat-Back (OEM cat retained) • Material: T304L stainless steel, hand-finished • Pipe Diameter: 80mm mandrel-bent • Resonance: Non-resonated (full acoustic character) • Tips: Burnt titanium finish • Installation: Direct replacement, OEM hangers compatible Milltek engineers this system for enthusiasts prioritizing sound character and flow over street-friendly refinement.
