Agency Power

High Flow Catted Stainless Steel Down Pipes BMW M3 F80 | M4 F82 | F83 Agency Power


One of the biggest restrictions of power on a performance car is corking up the exhaust gasses from the engine. Factory Down pipes 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 down pipe 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 down pipe is built from T304 stainless steel and then TIG welded. It utilizes the factory mounting points. Typically a down pipe will also give you a better flow to truly maximize its programmed potential.
