They're definitely high up there. I've seen some ITB setups around and they're pretty sweet. I actually just took a look at his, and it's definitely a cool get up.
Aside from that, thought about doing both paint and wrap? I've always thought about doing so, rather than just using titanium wrap, doing both, I would imagine, makes it so that any moisture trapped will be held in between the paint and the wrap. Wouldn't have to worry about rusting out the headers, then again I don't know how you'll be able to cure the paint though, and I've only ever thought about it, without much more thought.
