Overview

The VRSF 3" High Flow Catted Downpipe is an exhaust upgrade designed for BMW N54 135i and 335i models. By replacing the restrictive factory catalytic converters, these downpipes significantly reduce back pressure, leading to faster turbo spool, increased power, and a more aggressive exhaust note. The downpipes feature a full 3" diameter design that transitions to a 2.5" flange, optimizing flow.
Show original supplier description
The VRSF 3" High Flow Catted Downpipe is engineered to enhance the performance of BMW 2007-2010 335i (E90/E91/E92/E93) and 2008-2010 135i (E82) models equipped with the N54 engine. This downpipe offers a substantial performance upgrade, with claimed gains of 20-25 horsepower and 25-30 torque at the wheels when paired with a tune. The design minimizes back pressure by replacing the restrictive factory catalytic converters, resulting in quicker turbo spool and an enhanced exhaust sound. Constructed from hand-made, mandrel-bent, tig-welded SS304 stainless steel, these downpipes feature a CAD/CAM designed cast bell mouth for a seamless transition. Unlike some competitors, VRSF maintains a full 3" diameter piping up to the 2.5" flange to maximize flow. VRSF also offers optional, highly recommended turbo-to-downpipe clamps and gaskets for installations on vehicles with higher mileage. It is crucial to note that this specific catted downpipe is designed exclusively for Right Hand Drive (RHD) and Left Hand Drive (LHD) models. It will NOT fit Xi or X Drive all-wheel-drive variants. The product is compatible with 2007-2010 E90/E91/E92/E93 BMW 335i, 2011-2013 E92 BMW 335is, and 2008-2010 E82 BMW 135i. The manufacturer provides a lifetime warranty against defects and fitment, excluding the optional ceramic coating which has a 1-year warranty.
