VRSF is proud to introduce their VRSF 3″ Catless Downpipes for the N54 Z4 35i & 35is which now feature a cast stainless steel mouth. These 3″ downpipes are THE best bang for the buck mod available, with gains from 25hp & 30Nm 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 most of their competitors, their 3″ catless downpipe feature a full 3″ design up to the 2.5″ flange which allows an increase of flow. Their 3″ downpipes are handcrafted from SS304 stainless steel and include a lifetime warranty & they are “No Hassle” satisfaction guarantee which includes fitment & defects. Grade 12 installation hardware and gaskets are included with purchase.
