Default exhaust wrap, do headers get to hot?

I am considering wrapping my header in exhaust wrap.

My question is this:
Will header temperatures get high enough to damage the header with wrap?
Will excesive heat sink back into the head and cause engine damage?
Has anyone had an overtemp problem due to wrap?

I have a 2002 road king, mostley stock, no oil cooler, I am adding vance & hynes slip ons, dynojet power comander, and ness big sucker air filter.

I live near Boston, summer can hit 100 degrees once in a while.

I rarely go past 3500rpm, but I do like to feel the pull in 2nd and 3rd, so the throttle does get twisted, I just don't race it up, since it's not that kind of bike.

Cheers,

Jimbo

Any time you block the "cooling medium"...in this case, AIR...you dont transfer heat as well...that heat WILL find a sink.

Had them on my FLSTF and cracked the rear header pipe not worth the effort

Been running them covered for a couple years. No problems. Have seen some pipes that cracked, but it was probably due to poor design or shoddy construction of the pipes, and not from the wrap.

The idea behind them, aside from the looks, is to keep the exhaust gases hot so they flow faster.

Thanks for your input.
I might wrap them just to try it, I am keeping the chrome so I could always go back.
