AGENCY POWER CATLESS 3 INCH RACE DOWNPIPE - FORD (FOCUS ST)
Agency Power's 3" 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 with the attached hangers. As tested on a Mustang Dyno, the downpipe gave the ST about a 20hp gain with an additional 15ft. lb. of torque.
