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. - This product is intended for motorsport use only and requires 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.
