Palenon Performance B58 Downpipe Upgrade 2016+ BMW M240i/340i/440i/540i/740i & xDrive
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.
