Agency Power SS Catback Dual Exhaust for the Subaru WRX and STi has developed one of the best sounding and performing exhaust systems for the Subaru WRX and STi Sedan. The new exhaust features an all T304 stainless steel piping in 3inch 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 ½ inch thick flanges offer a secure fit along with the factory placement exhaust hangers.

The catback exhaust uses a high flow Y-Pipe to efficiently direct exhaust to the dual exhaust canisters. The Y-pipe features a merged collector and 3 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 catback exhaust features dual 3.5 inch quad tips with the Agency Power logo. As tested on a Mustang all wheel drive dyno, the Agency Power catback exhaust made an impressive 17 all wheel horsepower and 28ft/lbs of torque. 

All Agency Power products come with a LIMITED LIFETIME warranty

Great exhaust

Awesome sound, and a great clean look. The tips do a nice job filling up the open area the factory exhaust did not.

Great fitment + Sound!

Gives your wrx a great, throaty sound without making your ears bleed inside of the car. Definitely increased the performance of my sti. Fitment was good, the tips line up nicely. Gives you a nice boxer rumble without alerting the cops that it is anything but factory. I really like the tips, I'll leave the titanium tips for the kids, this exhaust flies right under the radar!
