One of the biggest restrictions of power on a performance car is corking up the exhaust gasses from the engine. Factory downpipes sometimes have smaller diameters and have very restrictive catalytic converters. Freeing up this exhaust flow is the easiest way to increase horsepower and torque through the RPM band. Agency Power’s stainless steel downpipe is a direct replacement for the factory pipe. Designed in a modular way so it can be used with the factory catback exhaust or an aftermarket catback, the downpipe is built from T304 stainless steel and then TIG welded. It utilizes the factory mounting points. Typically a downpipe will also give you a better flow to truly maximize its programmed potential.
