Just wondering what upgrades i should consider putting towards my sled, for weight and performance. maybe reeds or exhaust?

engine runs great but needs new exhaust gasket
and i want to get new ski's, and good plastic ones i should look at?

I didnt put much for upgrades on my vmax but i did put new skis on it, the sled already weighs a lot especially if it has electric start so i dont think plastic skis would make to much of a difference so save a few dollars and go with metal, i think i paid about 120 per ski and they are very durable and strong, i also sported for the red ski skins for about 30 bucks a pair, they screw onto the bottoms of the skis and add alot more protection and they look real sharp. happy shoppin.

i think im going with the usi x2 triple threat skis
any experience with them?
