APR's S4 Cat and Downpipe Exhaust replaces the the exhaust from the turbochargers to behind the lower factory catalytic converters. The system removes the factory pre-cats right off of the turbocharger and includes six separate components. Included are the two pipes off of each turbocharger, a set of pipes with catalytic converters, and a set of test pipes without cats. With TIG welding, fully stainless construction, and CNC'ed hangers, you will not find a higher quality downpipe system on the market.

APR's S4 Exhaust is a stainless steel, mandrel bent, cat-back exhaust. Our exhaust begins after the two lower factory catalytic converters and is two 2.25" pipes that merge into one 3" pipe. 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.

APR's S4 cat-back exhaust is available with two different sound levels. The Stealth exhaust helps to maintain the S4's subdued character. While louder than stock, it is not too loud to attract attention. The SRT exhaust replaces the center muffler with a special side resonator. This exhaust has a more aggressive sound and a distinctive note.
