Audi S3 2.0 TFSI quattro Sportback 8V/8V.2 (Non-GPF Equipped Models Only) From 2013 To 2018 Large-bore Downpipe and De-cat - Milltek Sport

Milltek Sport Large-Bore Downpipes are perfect when looking to improve both performance and sound. These downpipes are fabricated with a larger diameter than standard OEM parts, meaning that there is significantly more space for more gas to exit the engine and pass through, increasing efficiency. Used with our Catalyst Bypass Pipe, you can expect significant power-gain without any restriction on gas-flow made by a catalyst. - For Track Use Only! - For Fitment with the OE Cat-Back System only - Requires a Stage 2 ECU remap

Please note this exhaust is designed for motorsport use only. You will not pass a UK emissions test or police road side check with this exhaust installed on the vehicle.
