Description
AIRTEC Motorsport De-Cat Downpipe for BMW B58 Engine
By removing the original restrictive catalytic converter located within the factory OEM downpipe, back pressure is hugely reduced, which in return means faster response, increased power and a more aggressive exhaust note.
Supplied with an adaptor to marry up to the original exhaust system, it also fits aftermarket systems, making it the a perfect solution to replace the OEM downpipe.
One of the only manufacturers that offer a cast elbow to retain diameter!
