Overview

The Milltek Resonated Cat-Back Exhaust System is engineered specifically for the Audi B7 S4, delivering OEM+ fitment with a hand-finished T304L stainless steel construction. Direct factory fitment using OEM hangers-no modification required.

Constructed from premium T304L stainless steel with mandrel-bent piping and a 2.25" (57.15mm) diameter, this resonated system is tuned to eliminate drone while preserving the engine's full-throttle character. The resonance point is engineered to enhance the naturally aggressive B7 S4 soundtrack without compromising comfort on closed-throttle driving.
