It’s time to let the monster breathe! The B58 is an animal of a platform so long as you give it what it needs. The X-hale B58 downpipe fits the 2016+ M240i, 340i, 440i, 540i, 740i models along with the X variants. This downpipe removes the restrictive catalytic converter found in the OE downpipe and gives you an amazing high-flow cat. This allows your turbine to rotate more efficiently due to the fact it can remove the exhaust gases from the housing at a much higher rate. The X-hale B58 downpipe has been designed to reduce turbulence and increase flow by utilizing smooth radius bends. It is made of 4.5” 304 Grade Stainless Steel and is tig welded to ensure strength and longevity.

The Mock-up/ Race-Only X-hale Pipe is for Mock-up or off-road purposes only and is not to be used on any vehicle while it is running and/or used on public roads. The Mock-up pipe is designed to be used to test the fitment of your exhaust so you can complete your project without spending the full price of a high-flow catted downpipe before the project is complete. It is the exact same dimensions as our high-flow catted downpipe and the material is the same grade stainless steel however this is only a pipe. It does not contain a catalytic converter making it Illegal for use on any vehicle as it does not meet federal emission requirements. Once again this pipe is to test FITMENT ONLY before purchasing our High-Flow Catted Downpipe.
