The VRSF B58 High Flow Catted Downpipe optimises exhaust flow by replacing the highly-restrictive factory catalytic converter, and also adds to the aural experience. This is one of the best upgrades you can make to allow the B58 engine to truly perform in your F2X M140i/M240i or F3X 340i/440i. Please note that mapping to suit will be required to correct fuelling and avoid EML light.

These pipes bolt directly to the OEM system and use factory mounting locations. Not suitable for OPF models (July 2018 onwards) without an OPF delete. De-cat version also available.

• Made from hand-crafted, TIG-welded 4.5″ 304-grade stainless steel
• 200-cell sports cat for optimised flow
• Fits LHD and RHD models with no other modifications needed
• Smooth radius bends to decrease turbulence and increase flow
• Direct fit with the stock exhaust as well as aftermarket systems
• VRSF 1 Year Warranty
