Milltek Resonated Race Cat-Back Exhaust - Audi S3 8V Sportback - Polished Tips - SSXAU535

Milltek Cat-Back exhaust system for Audi S3 8V and 8V.2 Sportback (non-GPF models). Direct factory fitment using OEM hangers-no modification required. Engineered to replace the original system with improved tone and performance character while maintaining a resonated, refined note suitable for street and track use.

Hand-finished T304L stainless steel construction throughout, mandrel-bent for optimal flow. Quad oval polished outlet trims add aggressive aesthetics. Non-valved design delivers consistent character across the rev range. Decibel-tested engineering ensures the exhaust note is tuned, not loud-eliminating drone while enhancing full-throttle presence at the top end.
