No not mine and I actually don't own any...yet. I talked to cam who built my engine and he talked me into cpi for my current bike which is a fire road dune style. My FT ice bike will be SLP pipes under the recommendation of camatv who has tested them.
My powder coated here in Edmonton runs SLP on his stock cyl and stock stroke on hill climbs and he is fast! And his bike has half the mods as the guys he runs with. Also, he has been real happy with build quAlity, fit finish, and silencers. Hopefully camatv signs in, I know he has tested them along with redline
