TCM BMW S63 Catless Secondary Downpipes
Free Shipping Continental US
Upgrade from the restrictive stock S63 downpipes to the TCM catless downpipes for increased horsepower. Along with making the car sound more aggressive. The new downpipes will help your turbos spool quicker, so less turbo lag.
The TCM secondary downpipes are specifically designed to increase exhaust flow by removing restrictions and back pressure. They feature a mandrel-bent design to keep a consistent interior diameter throughout the pipe, ensuring smooth and fast flowing exhaust. This allows for quicker turbo spooling, faster throttle response, and increased horsepower and torque.
