Audi S7 Performance Exhaust - APR Cat-Back X-Pipe (Brushed, 2013-2018). Built to pair your 3-inch midpipes with an APR Catback, this add-on improves flow and refines the V8 soundtrack.

APR’s integrated X-pipe merges exhaust pulses to reduce backpressure and smooth tone, contributing to increased peak torque. Crafted in T304 stainless steel with argon-back-purged TIG welds and mandrel-bent dual 3-inch to 2.75-inch tubing, it’s engineered for durability and a precise fit. The kit includes new APR slip clamps and benefits from APR’s in-house design and rigorous quality control.
