The temp should never reach more than around 185, and thats just not that hot.. Ive got aftermarket pipes as well, and I've never experienced any type of Heat Discomfort. I mean, of course its going to be a little warm.. but it shouldnt be hot enough to cause discomfort...
I can take my hand and put it on the jug's fins at operating temperature. If you can't do this, something is up.
