Itโ€™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.ย 

B58 downpipe has been designed to reduce turbulence and increase flow by utilizing smooth radius bends. It is made of 4.5โ€ 304 Grade Stainless Steel and is tig welded to ensure strength and longevity.
