Overview

The VRSF 3.5″ downpipe is a direct bolt-on modification designed to reduce back pressure and increase power for BMW X3 and X4 models with the N55 engine. By eliminating the restrictive catalytic converter, this downpipe leads to faster turbo spool and a more aggressive exhaust note. It is constructed from hand-crafted, tig-welded SS304 grade stainless steel.
Show original supplier description
The VRSF 3.5″ Stainless Steel Race Downpipe is engineered to be a direct bolt-on performance upgrade for the N55 engine in select BMW X3 and X4 models. This downpipe significantly reduces back pressure by removing the restrictive factory catalytic converter, resulting in faster turbo spool, increased horsepower, and a more aggressive exhaust note. Available in both catless and high-flow catted versions, it offers a substantial performance gain. Constructed from hand-crafted, tig-welded SS304 grade stainless steel, this downpipe features smooth radius bends designed to decrease turbulence and increase flow. The turbo flange is precision CNC machined from billet 304 grade stainless steel. This downpipe is compatible with specific BMW models: the 2011-2017 BMW X3 xDrive35i (F25) and the 2014-2018 BMW X4 xDrive35i (F26), both equipped with the N55 engine and Pneumatic Wastegate (PWG). It is crucial to confirm that your vehicle is a PWG model, as this downpipe will only fit PWG cars with a 3.5″ downpipe outlet. VRSF offers a lifetime warranty on all their products, including this downpipe, ensuring satisfaction with fitment and defects.
