A downpipe is one of the first modifications that should be done on your car, as the OEM downpipe contains two very restrictive catalytic converters. Replacing these with our single high-flow unit will dramatically improve performance potential while maintaining the use of a catalytic converter. Our complete line of downpipes feature a high-flow, 300 cell catalytic converter, fully machined and contoured flanges and the option to add black ceramic coating. Whether you're racing time attack or to work and back, we've got the perfect downpipe for you.
