I know all snowmobiles leek exhaust. but I was wonding if it affects performance? where can I buy the stuff to stop the leeks?

Go to your local auto parts store and pick up a tube of Hi-Temp Ultra Copper silicone gasket material and put it on your exhaust connections before you slide it all together and let it sit for a couple of hours to dry, also you can put a bead of it on your springs after they are on and it will reduce a little vibration noise from those as well. :div20:
