Header Wrap

Does anyone know if it's legal to wrap headers in ITC?

Yes, it is. Exhaust is basically open, so long as its not over the sound limit and the exit is positioned right.

OK, thanks.

Header wraps are designed to keep the heat in the header to improve scavenging of the cylinders. Keeping the heat in the header allows the exhaust speed to remain high. If you do not mind replacing your headers and header gaskets regularly, and you like that ugly look of a wrapped header, go ahead and use the heat wrap.
