Description

The VRSF B58 is a downpipe designed to improve performance for BMW X3 M40iX and X4 M40iX models. It features a full 4.5-inch stainless steel construction with a CNC 304-grade stainless steel flange for a smooth transition from the turbo to the mid-pipes. This downpipe is available in both race and high-flow catted configurations.

By reducing back pressure and eliminating the restrictive factory catalytic converter, this downpipe leads to faster turbo spool, increased power, and a more aggressive exhaust note. It is crafted from hand-welded SS304 grade stainless steel and includes a lifetime warranty, though the catted version has a two-year warranty.
