Ok here is my 2 cents, but marinenyc is right you will get every pipe that a person has is the best, lol. MY opinion is that the PT mid-top pipes are the best all around pipes, they are great for a bike that isnt too hoped up on mods but will perform well with out any mods as well. When i first got my shee that is what it had on it and it was a pretty mild shee as far as mods and porting goes, but the pipes were amazing! Right now i have CPI's and I have to say they sound alot different, lol havn't gotten the shee to move since i rebuilt it but the CPI's are really different in many minor ways. My boyfriend runs shears and his shee is like a supper shee for a 4mil but it still is for the trails and dunes, i like the shears but they are definatly for a heavy porting.
