Milltek Large Bore Downpipe And Hi-Flow Sports Cat- RS3 8V/TTRS 2017+ (Facelift Only)

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.

– For Fitment with both Milltek Sport and OE Cat-Back Systems

– Stage 2 ECU Remap Required
