Mertop 3" Stainless Steel Catless Downpipes N54 E60 08-10 BM* 535i/535xi

These 3" 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.

We are proud to introduce our MERTOP 3" Stainless Steel Catless Downpipes for the N54 535i & 535xi. These 3" 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 like most of our competitors, our 3" catless downpipe feature a full 3" design up to the 2.5" flange which allows an increase of flow. Our 3" downpipes are hand crafted from SS304 stainless steel and include a lifetime warranty & our "No Hassle" satisfaction guarantee which includes fitment & defects. Grade 12 installation hardware and gaskets are included with purchase.
