VRSF High Flow Catted Downpipe For 2016+ BMW M240i/340i/440i/540i/740i/xDrive (B58)

We are proud to introduce our VRSF  high flow catted downpipe for your B58 M240i, 340i, 440i, 540i, 740i & xDrive variants. These downpipes are THE best bang for the buck mod available for your B58.

Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our race or high flow 200 cell race cat which results in faster spool, an increase in power & a more aggressive exhaust note. Our downpipe features a full 4.5″ stainless steel design as well as a CNC 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes.

Please note that the warranty on the catted downpipe is limited to one year.

Fits RHD and LHD models with no modification necessary.
Smooth radius bends to decrease turbulence and increase flow.
