Here at Agency Power we set out to develop one of the best sounding and performing exhaust system for the 2008 and up Subaru STI. This muffler-less exhaust features all T304 stainless steel piping that has been increased to 3inch diameter from the catalytic converter back. The piping is all hand polished featuring robotic TIG welding. The mid pipe 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 exhaust also features a quad exit stainless steel rolled tips with the Agency Power logo.

As tested on a Mustang all wheel drive dyno, this Agency Power cat-back exhaust made an impressive 20 all wheel horsepower and 20ft/lbs of torque. This Agency Power exhaust fits all Hatchback 2008 and up Subaru STI’s and 2011 up WRX. Designed to fit Hatch only. Does not fit 08-10 WRX

This Agency Power Exhaust system is available in the following configurations

• Black Ceramic Coating

(Ceramic Coating provides a hard finish which is resistant to rusting and chipping & lowers surface exhaust temperatures allowing for more horsepower)

• Stainless Tip
• Blued Titanium Tip

Check out the video below featuring a 2010 Subaru WRX STI Hatchback revving up and demonstrating the deep & aggressive exhaust note that is produced with this Agency Power Cat-Back Exhaust System.
