Agency Power has developed one of the best sounding and performing exhaust systems for the 2008 and up Subaru WRX Sedan. The new exhaust features an all T304 stainless steel piping in 2.5inch 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 boxxer engine sound with an exotic race tone touch that does not drone in the cabin. The 1/2 inch thick flanges offer a secure fit along with the factory placement exhaust hangers. The Turboback exhaust uses a high flow Y-Pipe to efficiently direct exhaust to the dual exhaust canisters. 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. The straight through mufflers are designed to optimize horsepower with very little restriction. The mufflers do feature removable exhaust silencers for those wanting the ability to keep the system very quiet during daily use. The turboback exhaust features dual 4 inch single straight exit Stainless Steel Tips with the Agency Power logo.
The downpipe is full stainless steel with a bell mouth upper section. The 0.4" thick flanges ensure a tight and strong seal. The downpipe deletes both your catalytic converters and bolts to all factory style turbos. The precision welds and mirror polishing piping give the Agency Power Racing Downpipe a show finish. Each downpipe includes a bung for an aftermarket air/fuel sensor as well as a bung for the factory O2 sensor.
