im thinkin of buying some kind of performance pipe for my grizz 600, but i dont want one thats loud,preferably not louder than a stock pipe.who makes one like this?

 

probably every aftermarket pipe is going to be a little louder than stock. the one i hear good things about is the Supertrap IDS 2, it can be tuned for either sound or performance it is pretty reliabe and it don't cost that much. no matter what you get never go with cobra. All they are mainly for is noise.

Hope this helps!!
