Subaru STI Hatch 08-14 | WRX Hatch 11-14 Agency Power Stainless Tip Catback Exhaust w/o Muffler
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 3inch 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 rolled stainless steel 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. The exhausts are available for all 2008 and up Subaru STI’s and 2011 up WRX.
Benefits
- T304 stainless steel piping
- 3inch diameter from the catalytic converter back

Please Note: Designed to fit Hatch only. Does not fit 08-10 WRX
