Okay, let me share some observations with you. When I first purchased my bike, the exhaust got so hot, it would burn my leg at stop lights. I had to move my bike once after a long ride and only enough time to shower, I ran out with shorts on, threw my leg over and scared my leg. My girlfriends brother took his wife for a ride on it and he burnt his leg also (after I warned him). It was beyond hot!
I took the exhaust off to do something and found my crown nuts had been torqued so hard that they froze to the studs. I replaced the studs (came off with nuts) that were the same size and thread at ACE Hardware. Put open face nuts and washers on (suggested on this site all over). Also noted there was 4 crush gaskets in the head instead of 2 (suppose to be only 2). After installing new crush washers, it was much cooler (I had the same style set up as you).
Then I went to V&H Exhaust. Wow, what a world of difference, I do not feel even the slightest heat issue. I might even be able to wear shorts on it if I am going on a Gold wing parade or something?
Here is a thread on the V&H exhaust. http://www.vtxcafe.com/showthread.p...und-to-installing-the-Vance-amp-Hines-exhaust
I have more pictures but, I am spending too much time looking. If you have any more questions, feel free to contact me.
