A VRSF 3.5" Catted downpipe for the N55 135i & 335i is THE best bang for the buck mod available for the N55, offering gains ranging from 25-30hp 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.

VRSF 3.5" Catted Downpipes for the N55 135i & 335i which
now feature a cast stainless steel mouth. These 3.5" downpipes are THE
best bang for the buck mod available, 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 as
competing systems do, VRSF's 3" Catted downpipe features a full 3"
design up to the 2.5" flange which allows an increase of flow.
downpipes are hand crafted from SS304 stainless steel and include a
lifetime warranty & VRSF's "No Hassle" satisfaction guarantee which
includes fitment & defects. Grade 12 installation hardware and gaskets
are included with purchase.
