2011-14 WRX & STi Sedan Agency Power Catback Exhaust


Agency Power has taken its experience with developing new exhausts to the new STI sedan platform. This quad tip, dual muffler exhaust features 3", T304 stainless steel piping, TIG welded mandrel bends and a polished finish. The design utilizes factory mounts to ensure easy installation. The midpipe includes a resonator to assist in keeping that traditional Boxer engine sound with an exotic race tone touch that does not drone in the cabin. The free flowing design allows for greater exhaust evacuation giving your car a huge boost in performance, quicker turbo spool, and an improved exhaust note. The catback exhaust features quad 3.5" tips with the Agency Power logo. During testing on a Mustang all wheel drive dyno, this catback made an impressive 17 AWHP and 28ft/lbs of torque!
