Description

The Milltek 2.50" Non-Resonated Cat-Back Exhaust System is engineered for the Audi B9 S4 and S5 3.0 V6 Turbo (Sport Differential models without brace bars). This direct-fit replacement delivers enhanced exhaust flow and an aggressive, pronounced tone character. Constructed from T304L stainless steel with CNC-formed quad GT-100 Cerakote Black trims, this system uses OEM hangers and requires no modification for installation. The non-resonated design eliminates stock resonance chambers, maximizing full-throttle note intensity while maintaining OEM+ fitment precision.
