The ideal light-weight exhaust (just 29lbs.) for the R35 GT-R is the 94mm GReddy Supreme TI.

The large dual oval mufflers provide excellent sound suppression and sound quality, while large piping frees up power for the twin turbo VR engine. This version comes with a huge dual 80mm (3.15") to 94mm (3.7") Y-pipe. The construction is made up of carefully hand-built 94mm piping is pain-painstakingly "inch-welded" for excellent fitment and flow.

With full Titanium construction, the GReddy Supreme Ti  Exhaust features our original Dual 60-70mm Titanium piping to Quad 60mm Titanium piping to the two Dual inlet Titanium oval mufflers.
