Need a regulator and exhause for my 350x

Thats what I need. I need one cause mine burnt out. My exhause is dead too. Can you tell me which one is the best to buy for the best price?

ok, for one its "exhaust", check on ebay, pipes dont make much of a difference on 4 strokes, but i have heard good stuff about supertrapp
