VRSF N54 Catted Downpipes - For RWD 135/335 Vehicles

We are proud to introduce our VRSF 3″ 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 of our competitors, our 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 & our “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. We also offer additional installation accessories such as the turbo to downpipe clamp and gasket available for purchase separately. While the turbo to downpipe clamps and gaskets aren’t required for installation, they are highly recommended if your original accessories have more than 50-60k miles.

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

Note: The catted version is limited to LHD fitments.
