VRSF - Stainless Steel Downpipe - BMW N55 (E-Chassis)

We are proud to introduce the VRSF 3.5" catless or catted downpipe for your N55 (E-Chassis). The 3.5" downpipe is THE best bang for the buck mod available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.

This downpipe feature a full 3.5" stainless steel design as well as a cast 304 grade stainless steel merger that offer a smooth transition from the turbo to the mid pipes. All VRSF downpipes are hand crafted from SS304 grade stainless steel and include a lifetime warranty as well as their "No Hassle" satisfaction guarantee (includes fitment). Grade 12 installation hardware and high quality steel gaskets are included with purchase.

- Made from hand crafted, tig welded 3.5" 304 grade stainless steel.

- Smooth radius bends to decrease turbulence and increase flow.
