Audi S3 Performance Exhaust - APR - Catback - 2015-2017. A hand-crafted T304 stainless system that refines tone and improves flow while preserving factory valve control.
Designed in-house for the 8V S3 Sportback, this APR catback combines straight-through, brushed-finish mufflers with a Helmholtz resonator to cut unwanted frequencies and deliver a deep, composed growl without added restriction. A cast 3-inch to quad 2.5-inch splitter and mandrel-bent tubing increase cross-section versus stock with no increase in weight. OEM-style slip clamps, Torca AccuSeal tip clamps, rugged brackets, and a low-profile layout make the direct bolt-on install precise and service-friendly. Cast valve housings accept the factory electronic actuators for full OE valve operation. Note: fits S3 Sportback (8V) and T-Roc (ROW market); for S3 Sedan use CBK0003.
