Invidia [08-14 WRX/STI] Q300 Cat-Back Exhaust - Single Rolled Stainless Tip
The Invidia Q300 Cat-Back Exhaust for the 2008-2014 Subaru WRX sedan and 2011-2014 Subaru WRX STI sedan (GR/GV chassis) pairs the Q300's deep, refined touring tone with a single-exit rear. Built from 76mm mandrel-bent SUS304 stainless steel with CNC-machined flanges and robot TIG welds, its flat-bottom muffler uses continuous piping and Advantex material for excellent free flow with optimized back pressure and the Q300's deep, rich sporty sound, finished with a single 110mm rolled stainless steel tip. All gaskets and hardware are included for a direct bolt-on fit.
