Im on second set of Hooker fenderwell headers for BB (avatar) because of header wrap.
Did it for mainly keeping MC and brake lines cooler. Condensation promoted pinholes
at thinner bends of header.
However, I think the more you drive it, better off you are. Moisture is burned off in/around wrap. The lesson I learned, if you dont drive it few times a month, forget
the wrap, I did...........
