For your 2014+ BMW M3 & M4 with the S55 Engine
We are proud to introduce our 3" cat-less downpipes for the S55 F80/F82 M3 & M4 which are one of the only downpipes to feature a cast stainless steel v-band to pipe transition. These 3" downpipes are the best bang for the buck mod available for your S55, with gains from 25hp & 30tq when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
Rather than necking down closer to the turbos like most of our competitors, our 3" cat-less downpipes feature a full 3" design up to the last couple of inches of the pipe which allows an increase of flow. Our 3" downpipes are hand crafted from T304 stainless steel!
