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. Combined with our Hi-Flow Sports Cat, you can expect a significant increase in performance and a noticeable difference in sound aesthetic. - Requires Stage 2 ECU Remap.- Fits with Milltek Sport cat back exhaust system only - Requires 2 x 18307851168 Lambda Extentions for installation (available from local BMW dealer)
