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!
