The APR Catback Exhaust System for the Audi C8 RS6 and RS7 runs from the catalyst back, including downpipes and oversized oval tips. Crafted from mandrel-bent T304 stainless steel with TIG welding, it delivers a bold growl, 9 HP and 16 FT-LBS of torque gains, and features an integrated Helmholtz resonator to minimize drone.

With valve-controlled mufflers for dynamic sound adjustment and dual 3-inch piping, this system balances daily civility with track-ready aggression. Precision brackets, slip clamps, and diamond black RS-style tips complete a refined, high-performance upgrade.
