APR's A3 Exhaust is a stainless steel, 3.0" mandrel bent, turbo-back exhaust. Unlike most other aftermarket exhausts, the APR exhaust is a full exhaust from the turbocharger back. 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. All APR exhausts come with a full lifetime warranty.

On the A3, the stock exhaust is almost 2.5" and flows very well even on a chipped car. Simply adding an exhaust to a stock or chipped 2.0T does not make a very big gain over the stock setup. Unlike the 1.8T, because of the new engine management (ME9) and FSI, there are substantial gains that can be seen by making a software change after adding the exhaust.

With APR exhaust-specific software, peak gains of 18hp and 20lb-ft can be seen. At some RPM's, these gains are as high as 22hp and 25lb-ft. APR exhaust-specific software is available for free for all APR ECU Upgrade customers.
