Show original supplier description
The VRSF B58 Downpipe Upgrade is a performance exhaust component designed to enhance your B58-powered BMW. This upgrade replaces the restrictive factory catalytic converter, significantly reducing back pressure. This reduction leads to faster turbo spool, an increase in horsepower and torque, and a more aggressive exhaust note. The downpipe is constructed from hand-crafted, tig-welded 4.5" SS304 grade stainless steel, featuring a CNC 304 grade stainless steel flange for a smooth transition from the turbo to the mid-pipes. It is available with an optional high-flow 200-cell race cat, though this option carries a one-year warranty, unlike the race version which includes a lifetime warranty. It is compatible with both Right-Hand Drive (RHD) and Left-Hand Drive (LHD) models. This downpipe is compatible with a wide range of BMW models equipped with the B58 engine, including the 2016-2022 M240i/M240i xDrive (F22/F23), 2016-2022 340i/340i xDrive (F30/F31), 2016-2022 440i/440i xDrive (F32/F33/F36), 2016-2022 540i/540i xDrive (G30), 2016-2022 640i/640i xDrive (G32 GT), 2016-2022 740i/740i xDrive (G11/G12), and 2018-2022 840i/840i xDrive (G14/G15). A tune is recommended to fully realize the gains of up to 25-30hp.
