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!
