Supreme SP Cat Back Exhaust by Greddy

A large horizontally mounted, 3-section muffler with a center inlet and an unique, tuned, internal "Y-pipe." This directs exhaust gases through a center chamber to reduce overall sound and improves flow to the outer straight-through sections. These outer sections of the muffler have our updated high-temp, internal sound suppression system. The exhaust is finished-off with dual GReddy slant-cut, double-walled tips in the factory bumper outlets. This cat-back exhaust also uses a simplified exhaust pipe routing with a large straight-through resonator in the mid-pipe, to tune-out any drone. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries.
