Agency Power Titanium Tip TurboBack Exhaust Subaru STI Wagon 08+

Agency Power has developed one of the best sounding and performing exhaust systems for the 2008 and up Subaru STI. The new exhaust features all T304 stainless steel piping in 3 inch diameter from the catalytic converter back. 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 muffler is designed to optimize horsepower with very little restriction. The turboback exhaust features a quad exit Titanium Tip 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.
