Man I just can't remember the model number but it is actually one of their universal ones. They make two of them. One is for up to a 200cc model and one is 200cc to 500cc. They are actualy both for 2 stroke models. The main difference I could tell is that one has a 1 and 1/8 inch inlet and the other has a 1 and 1/4 inch inlet. I'll see if I can find the exact model numbers.

Thanks for the help.

the exhaust muffler isn't as near important as the size and shape of the pipe running from the head to the muffler. but replacing the stock muffler alone will help. Here's the one you will want to use. http://abc.eznettools.net/ez-catalog/X329438/7/375
stay away from 2 stoke pipes. they are set up different from 4 stroke pipes and can sometime hurt more than help. It has all to do with pulse timing, valve overlap, size, shape, and a lot of other techno jumble.

check your jetting after you add the pipe. With your present set up ,you may need to go up to a 127.5 jet
