The 2015 Subaru WRX STi showcased in the video features the Agency Power Catback Exhaust System with Polished Quad Exhaust Tips. This system is also available in a Blued Titanium Tip option seen HERE

The exhaust features an all T304 stainless steel piping in 3inch diameter from the catback. The piping is polished featuring robotic TIG welding and 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 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.
