Audi S4 B6/B7 4.2L Performance Exhaust System

APR's B6/B7 S4 Exhaust is offered as both a full or as a catback system. The catback system is a complete stainless steel, mandrel bent, cat-back exhaust. The exhaust is a dual 2.5" system that begins at the factory downpipes and continues to an innovative center muffler. The exhaust then splits and each mandrel bent pipes goes to its own muffler with a 3.5" (90mm) bevel-cut, round tip for the B6 S4, or dual 3" (75mm) for the B7 S4.

This exhaust is very quiet and simply changes the tone of the exhaust to a deep, unobtrusive sound. With TIG welding, fully stainless construction, and CNC'ed hangers, you will not find a higher quality system on the market.
