N55 PWG Stainless Steel Race Downpipe

The VRSF 3.5″ Stainless Steel Race Downpipe is engineered to be the premier performance modification for BMW vehicles featuring the N55 engine and a Pneumatic Wastegate (PWG). This upgrade significantly reduces exhaust back pressure by eliminating the restrictive factory catalytic converter, which translates into quicker turbocharger spool, noticeable gains in horsepower, and a more aggressive exhaust tone. A key feature is its uniquely designed CFD-optimized cast merge collector, which facilitates the smoothest possible transition from the turbocharger to the mid-pipe, enhancing overall exhaust flow efficiency. Crafted with precision, every VRSF downpipe is meticulously hand-fabricated using tig-welded, mandrel-bent 304-grade stainless steel tubing, ensuring superior strength, corrosion resistance, and consistent performance. The downpipe utilizes CNC SS304 stainless steel flanges for a secure and leak-free connection. This downpipe is compatible with both right-hand drive (RHD) and left-hand drive (LHD) vehicles. For vehicles with over 60,000 miles, VRSF highly recommends purchasing the optional turbo clamp and gaskets to ensure optimal installation and longevity. The product is backed by a comprehensive VRSF lifetime warranty, covering defects in material and workmanship, as well as fitment. For guaranteed fitment, customers may be advised to send a picture of their wastegate and downpipe to catback flange from the engine bay for verification, especially for earlier production models. This downpipe upgrade is specifically designed for the following BMW applications: 2011-2016 BMW 535i & 535Xi (F10 & F11), 2011-2016 BMW 535i & 535Xi Gran Turismo (F07), 2011-2017 BMW 640i Coupe & Convertible (F12 & F13), 2011-2015 BMW 740i & 740LiX (F01 & F02), 2009-2013 BMW X5 35iX (E70), and 2009-2014 BMW X6 35iX (E71). It is crucial to verify the Turbo Wastegate type (PWG) for relevant models.
