Product Description
Milltek Large Bore Downpipe and Hi-Flow Sports Cat for B9 SQ5
THIS ITEM CAN NOT BE SHIPPED TO CALIFORNIA CUSTOMERS!
*Fitment Note: Stage 2 ECU software required*
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.
