I recently added a sno-stuff rumble pak silencer on my '01 mxz 700. The destructions say no jetting is necessary but they do say you should run 92 octane fuel. Any one else have one, no snow to test it. it does have a nice bark to it. * * * * * * * * * * * * * * *Thanks.

My buddy had 2 on his 2001 700 broke the weld twice
