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!
