The right side of our Summit X Project houses a Diamond S Titanium exhaust can. We chose the quiet version and it tips the scales at a svelte 3 pounds. No tickets with this can....it's really quiet. We eliminated the stock chain, gears, and cover with a TKI Belt drive kit which shaves another 7 ponds and is smooth as glass. This sled spools up quick and it is noticeably quieter in the driveline with the belt drive. We installed a 1.95 ratio for trail riding and will get a 2.33 ratio for the mountains with a simple change of the top gear.
