Agency Power has developed one of the best sounding and performing exhaust systems for the Subaru WRX & Subaru WRX STi Sedans. The exhaust features an all T304 stainless steel piping in 3inch diameter from the catback. The piping is polished featuring robotic TIG welding. The mid-pipe includes a resonator to assist in keeping that traditional boxxer engine sound with an exotic race tone touch that does not drone in the cabin. The ½ inch thick flanges offer a secure fit along with the factory placement exhaust hangers. The catback exhaust uses a high flow Y-Pipe to efficiently direct exhaust to the dual exhaust canisters. The Y-pipe features a merged collector and 3 inch piping on each extension to maximize exhaust flow. The straight through mufflers are designed to optimize horsepower with very little restriction. The catback exhaust features quad 3. 5 inch tips with the Agency Power logo. As tested on a Mustang all wheel drive dyno, the Agency Power catback exhaust made an impressive 17 all wheel horsepower and 28ft/lbs of torque. The exhausts are available for 2011-2017 Subaru WRX & 2011-2017 Subaru WRX STi Sedans.
