Greddy Supreme SP Cat-Back Exhaust, 2011-2014 STi (Sedan)

The Supreme SP for the Subaru STI Sedan features much larger diameter piping, resonators and mufflers, but also smoothes the layout for maximum performance with good sound suppression. This cat-back exhaust starts out with a full 3" mid-pipe with a large straight-through resonator to tune out drone. The next section smoothly transitions into dual 2.5" diameter piping. Improved dual GReddy straight-through mufflers with dual, double wall tips on each muffler finish off the exhaust. GReddy designers carefully position the dual mufflers and staged tips to flow with the GV-chassis' bodylines.
