Upgrading your Audi’s restrictive factory downpipes with a new APR downpipe exhaust system is a great way to significantly increase performance and throttle response whilst adding a dynamic growl to the exhaust note. The Audi S3 2.0T downpipe system 

is designed, developed and manufactured in-house at APR, utilising a larger 76mm Premium T304L stainless steel and mandrel bend construction to deliver unmatched performance, quality, and reliability.

The system is supported by a GESI high-flow catalyst which reduces emissions, smell and noise over catless setups without the performance hit. For those seeking APR Stage 2+ performance, a APR downpipe system is required.

Otherwise for those only seeking a change in exhaust note a Milltek cat-back system is recommended. With over 34 years of continuous exhaust development, Milltek Sport exhausts offer an ever-expanding comprehensive selection of performance products which will suit the needs of your Audi, whether it is a standalone upgrade or working in conjunction with supporting modifications to deliver high-level performance.
