Supreme SP Cat Back Exhaust by Greddy
The Supreme SP much larger diameter piping, resonators and mufflers, but also smoothest 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. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust.
