Product Description
Agency Power has developed one of the best sounding and performing exhaust systems for the 2008 and up Subaru STI. The new muffler-less 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 catback exhaust features a quad exit titanium tips with the Agency Power logo.
As tested on a Mustang all wheel drive dyno, the Agency Power catback exhaust made an impressive 20 all wheel horsepower and 20ft/ lbs of torque.
Fitment:
- Subaru STI Hatchback 08-14
- Subaru WRX Hatchback 11-14
Note: Designed to fit Hatch only. Does not fit 08-10 WRX
