Ok, after finally getting about 10 rides on the carls pipe on my 22 850 between Washington concrete snow and McCall, ID snow I figured I would repost an update. Short answer is I like the pipe. Long answer is I did a few to many changes ( pipe, slp head, lighten and balanced clutches and Trs clutch kit) all at once. 1) here is what I can tell you even with all the foam removed from under the hood and side panels I’ve had zero melting issues. I recently had a a very long wide open pull in a large chute and everything was still in factory shape body parts wise. 2) I’ve ridden over the hood powder many days and zero cold pipe bog issues. I honestly kept waiting for it and it never did. 3) she sings at 8450-8500. Seems like she like that higher rpm (could be the head or pipe or both) I try and keep it clutched for below 8400 to be safe though. 4) I do feel a slight weight difference when blipping the throttle to point the frontend a different direction. 5) zero DET issues 6)only possible down fall because I don’t normal ride about 7,000ft is about 8,000ft she seems to lose some power wide open on longer pulls/sidehills. That could be the head, pipe or me (the rider) just not used to 8,000 ft elevation riding. Over not a bad upgrade for small price.
