VRSF 4 Inch Brushed Race Decat/Catless Downpipe for BMW N55 EWG (Post July 2013) - 535i F10/F11/F07 GT, 640i F12/F13, X5 35i F15, X6 35i F16 - SS304 Bolt-On

Four inch race de-cat front pipe for BMW N55 electronic wastegate models

Unleash your N55 with this four inch high-flow race pipe. Expect quicker spool-up, sharper throttle response and a deeper, more purposeful soundtrack thanks to reduced backpressure and a freer flowing turbo outlet. Built from premium 304-grade stainless with a brushed finish, smooth-radius mandrel bends and precision TIG welds, this performance exhaust front section is a direct-fit upgrade for post 07-2013 N55 EWG vehicles and is one of the best value power adders before a remap.

We run this part on our own builds and feedback from our customers has been outstanding for fit, sound and gains. It is the ideal foundation for a Stage 2 calibration, delivering noticeable increases in bhp and torque along with lower exhaust gas temperatures.
