VRSF - Stainless Steel Catless Downpipes - BMW F8X M3/M4
We are proud to introduce the VRSF 3" Catless Downpipes for the S55 engine (F8X 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, backpressure 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 other downpipes, VRSF's 3" catless downpipe feature a full 3" design up to the last couple of inches of the pipe which allows an increase of flow. Their 3" downpipes are hand crafted from SS304 stainless steel and include a lifetime warranty & their "No Hassle" satisfaction guarantee which includes fitment & defects. Grade 12 installation hardware is included with purchase.
