Agency Power is well known for it’s Subaru parts, and is about to release a NEW Quad Tip Exhaust for the 2011+ Subaru WRX STi.

Agency Power has developed one of the best sounding and performing exhaust systems for the 2011 WRX STi Sedan. The new exhaust features an all T304 stainless steel piping in 3inch diameter from the catback. The piping is all hand polished featuring robotic TIG welding. The midpipe includes a resonator to assist in keeping that traditional boxer engine sound, with an exotic race tone 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 polished mufflers. The Y-pipe features a merged collector and 2.5 inch piping on each extension to give your exhaust a combined 5 inches of exhaust flow.
