VRSF Stainless Steel Catless Downpipe - 10-17 BMW 550i/550xi/650i (F10/F11/F12)

We are proud to introduce our VRSF 3″ Catless Downpipes for the N63 F06/F10/F12/F13/F15 M5 & M6 which feature a CNC stainless steel v-band to pipe transition. These 3″ downpipes are the best bang for the buck mod available for your N63, with gains from 50hp & 60tq when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, backpressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
