Large Bore Downpipes with Catalyst Bypass Pipes (For OE Cat-Back)

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.

We also remove the primary catalyst from the exhaust system to create more of a freer-flowing exhaust, allowing the engine to operate more efficiently and to increase performance.
