APR's A4 Exhaust is a stainless steel,
2.5" 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 downpipe. 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 is in the process of forming a
complete line of exhaust upgrades for your A4. Whether for street or
track use we will have the right application for you!
