Audi RS6 Performance Exhaust - APR - Cat Back - Diamond Black - '21-'25. A premium cat-back for the C8 RS6 that delivers a deeper tone and valve-controlled civility.
This APR cat-back runs dual 3.0 in piping and straight-through mufflers when the valves are open for a clear path. An integrated Helmholtz resonator helps curb drone on the open route; closing the valves diverts flow through a quieter 2.5 in path. It finishes with RS-style oval tips (8.23 x 4.76 in) in diamond black with a subtle APR logo. Built from mandrel-bent T304 stainless with TIG welds, and secured by precision brackets and OEM-style slip clamps. Designed for a precise fit on 2021–2025 RS6 (C8). APR reports gains up to 9 hp and 16 ft-lb at the wheels.
