Recently I've been considering pipe wrapping the exhaust on my Baja Bug because it's starting to get some surface rust and it looks dumb. I've read that wrapping the exhaust can help in keeping engine temps down, which would be awesome, especially when the weather starts to warm up here in STL. I've also read that pipe wrap can promote rust because it holds in moisture, but I don't drive my Bug in the rain at all, so I don't think that would be a problem.

My question to you guys would be: do you think pipe wrap is a good idea or should I just forget about it and paint my exhaust? Here's the current state of what my pipes look like.

Have an R8 that I just spotted as payment for your time.
