I have a touring that got crazy hot if I ever got stuck in traffic. I pulled the chrome exhaust shields off, wrapped the header down to the single outlet with header wrap, and then reattached the heat shields. I didn't have a heat gun to check it, but my right leg wasn't on fire in jeans and boots anymore, even at 100 degF in Mid TN summers. I think the comment about removing the CAT's is relevant; they build a lot of heat and expand a bit at operating temps. Getting some aftermarket pipes sans the CAT's could go a long way. In the meantime, $30 worth of header wrap seemed to cut down the radiant heat from the exhaust and pushed a lot more out the back end. I also started running a different tune that has the radiator fan kicking on at a slightly lower temp than stock. I've found this helpful, too. Good luck!
