APR's cat-back exhaust for the RS3 (8Y) is built from T304 stainless steel with dual 63.5mm mandrel-bent brushed tubing and TIG welding throughout. Cast valve housings accept the factory electronic valve actuators to retain OEM valve operation and variable sound levels, while straight-through brushed sound-absorption mufflers deepen the note without rasp or added restriction. Quad 63.5mm outlets route out through the factory RS bumper-integrated exhaust tips. The low-profile system mounts with OEM-style slip clamps for a plug-and-play install.
