Description

The Milltek 2.50" Non-Resonated Cat-Back Exhaust System is engineered for the Audi B9 S4 and S5 3.0 V6 Turbo, delivering enhanced exhaust flow, dyno-proven performance gains, and an aggressive engineered tone. Direct factory fitment-no modification required. Constructed from T304L stainless steel and hand-finished with quad Cerakote Black oval tips, this non-resonated system is mandrel-bent throughout for maximum flow efficiency. The 2.50" (63.50mm) bore eliminates resonance peaks at cruise and full-throttle operation points, allowing the signature V6 turbo character to dominate across the RPM range. OEM hangers and direct bolt-on fitment ensure seamless installation on compatible platforms.
