Removing the factory downpipe and adding a high flow downpipe is a fast and efficient way of adding power to your car. Factory downpipes are often constructed from restrictive piping, baffled resonators, and restrictive catalytic converters. By adding a free flowing downpipe, your vehicle's engine can breathe better. This results in less turbo lag, more power, increase fuel economy, and better throttle response. For Offroad/Motorsport Use Only
