Agency Power Catback Exhaust System with Dual 4" Stainless Steel Tips Subaru WRX STI Sedan 08-17
The Agency Power Catback Exhaust System for the 2008-2017 Subaru WRX & STI is now available in a dual 4" tip configuration that offers performance and sound that is unsurpassed! The system is manufactured using T304 stainless steel piping in 3 inch diameter from the catback. The piping is all hand polished featuring beautiful TIG welds throughout the entire system. The mid-pipe includes a resonator that aids in keeping the traditional boxer engine sounding mean and aggressive, while being drone free! The ½ inch thick flanges provide precision fit and a secure fit along with the factory placement exhaust hangers. The catback exhaust uses a high flow Y-Pipe to efficiently direct exhaust gas to the dual exhaust canisters. The Y-pipe features a merged collector and 3" inch piping on each extension. The straight through mufflers are designed to optimize horsepower with very little restriction. The mufflers do feature removable exhaust silencers for those wanting the ability to keep the system very quiet during daily use. The exhaust is available in either 4" Stainless Steel tips or 4" Dual Titanium Tips!
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. The exhausts are available for all 2008-17 Subaru WRX | STI Sedans.
