I have wrapped CATs in the past but never head pipes. Not good for daily drivers as it is very hard on the tubing.
If your ECM is properly tuned head heat and exhaust heat will come down. Made a big difference with our TC engines.

On mine. I experience heat as well but not really on my foot, its the back of my calf. My passenger doesnt notice any excessive heat but Idk how. Mine still has the cat. I shot pipes with a thermometer and it runs about 250 on the headpipes but at cat over 400. I dont see how removing the cat wouldnt cool it down. If its that hot on your foot, Id look at dyno tune even if its been tuned in the past. You may have got a bad dyno man or he may have had a shitty day at work that day. Be 100% sure the cat is removed also.

Hmmm, will take a look at those V&H again. I still have them. I have to pull the header off this winter, gonna check my cam chain adjusters. Almost 71K on the clock, so it's time. The lowered and moved floor boards would not work for me. Lol, at 5'6" it would be a real stretch just to get my feet on em.

Insulation keep heat in and out. If the heat is staying in the pipes, its not getting out to you. That is a given.
The damage to the pipes, if I did it, is a known risk. I doubt I would have a hard time locating a header pipe for a twin cam, if it came to that.

I think Buell95 nailed it as best answer as they are not wraps as they are actually insulators. Even have insulators for your stock and the V&H you have! Link attached below. Design Engineering
One more thing about your tune as I have had 100% great results myself with FM tunes, especially if you follow up and being a stage 1 is not too difficult.
Do you have the PV tuner you can mount on bars and watch as you ride? You could watch your AFR as you ride and see where it is running. But as you said the auto tuning you have done should have taken care of this.
