Description

Direct factory fitment non-resonated cat-back exhaust for Audi B9 S5 Sportback with Sports Differential and Factory Brace Bars. Hand-finished T304L stainless steel system engineered to deliver maximum sound character and performance gains on closed-course and track applications.

Mandrel-bent 2.5" diameter piping with CNC-formed quad polished tips (4" GT-100 round or quad oval available in polished stainless or Cerakote Black finish). Direct bolt-on replacement using OEM hangers and mounting points-no modification required. Non-resonated design eliminates mid-range drone characteristic of resonated systems, delivering full-throttle engagement across the entire powerband.
