Model Number: AP-GRB-170
Agency Power Titanium Tip Catback Exhaust Subaru WRX STI Wagon 08+
Agency Power has developed one of the best sounding and performing exhaust systems for the 2008 and up Subaru WRX STI. The new 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 muffler is designed to optimize horsepower with very little restriction. The catback exhaust features a quad exit Titanium Tip 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 WRX STI Wagons.
