Engineered Performance for Audi, VW, Porsche & Skoda

APR's A4 Exhaust is a complete stainless steel, mandrel bent, cat-back exhaust. On an A4, the catalytic converter is bolted to the turbocharger and then the exhaust begins with the downpipe. Unlike most other aftermarket exhausts, the APR exhaust includes a 2.5" downpipe. The exhaust then continues back to the innovative center muffler, where it splits into dual 2.25" pipes. Each of these mandrel bent pipes goes to its own muffler with a 3.5" rolled, round tip.
 
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.
