My FSM indicated that to remove rear wheel I had to remove rear exhaust. Did that but muffler would not separate from header pipe so I removed all in one piece. I can twist the header a little but no way it is separating from from the muffler. I can see where there is rust in the joint. So I tried penetrating oil and no difference. Should I use the torch or maybe a heat gun which I have? Don't want to manhandle and mess up the chrome. TIA

 

WD40 the s**t out of it and leave overnight.
If that doesn't do it try some vibration and/or heat.

 

Heat gun sounds like a good idea.

 

Thanks, I used both WD and the heat gun as well as a cheapo strap wrench from HF and finally got the sucker loose. Going to wire wheel the joint and put back together with some copper grease.

 

I use wd40,

 

I had the same issue when I tried removed my muffs. Here is a recent link to a thread for solution to my problem. You can read the entire thread on steps to remove muffs or from post #25 on your specific issue. Hope it will help you.
