APR builds this catback exhaust system for the Audi S3 Sedan (8V) from hand-crafted T304 stainless steel, TIG-welded throughout for a finish that matches its performance. SKU CBK0003. Straight-through mufflers open up the exhaust note without adding restriction, while a Helmholtz resonator keeps unwanted drone in check.
