VRSF BMW 135i/335i N54 3" Racing Downpipe Upgrade (E8X/E90/E92/E93)

VRSF is proud to introduce the 3-inch High flow Downpipes for the N54 135i & 335i. These 3″ downpipes are THE best bang for the buck mod available, with gains from 30hp & 35tq when when paired with a DME remap. By replacing the restrictive catalytic converters in the factory N54 downpipes, back pressure is significantly reduced which results in faster spool, an increase in power & a more aggressive exhaust note.

Rather than necking down closer to the turbos like most downpipes, VRSF's 3″ N54 downpipes feature a full 3″ design up to the 2.5″ flange which allows an increase of flow. These downpipes are hand crafted from SS304 stainless steel and include a lifetime warranty & a “No Hassle” satisfaction guarantee which includes fitment & defects. Each kit includes heavy-duty, grade 12 bolts, nuts and washers along with two mid-pipe gaskets.

VRSF also offer a ceramic coated version which is made to withstand temperatures up to 1800F. Please note that while they do offer a lifetime warranty on the downpipes, they only offer a 1-year warranty on the ceramic coating services due to the nature of the coating.
