What a great looking header system!

Just my two cents.

The biggest reason to insulate exhaust it to keep it from cooling along its way such that the gases slow down and increases back pressure.

With such a short exhaust with two mufflers, not sure wrapping will help. Susptct if the waste gate is open, there is plenty of gasses to run the turbo without trying to retain heat. Only the dyno will tell.

Another reason to wrap an exhaust is to protect things near it from heat.

Coating or raping the header section might have more potential. That would insulate the primary tubes from the cooling air and the top end from radiant heat.

Just an unsolicited opinion, if that is not a cat right after the turbo, I would probably work to remove it. The section right after the turbo exit is suposed to be a bit more important.

Still, I think the wrap looks really cool.
