The VRSF B58 Catless 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 as they replace the primary catalytic converter, these can result in MOT and emissions issues, and 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. Sports cat version also available.

• Made from hand-crafted, TIG-welded 4.5″ 304-grade stainless steel
• 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 Lifetime Warranty

Please note that removal of emissions equipment is not MOT compliant and so these parts are for off-road use only.
