Anybody ever do this on your Mk1 before? I had the cracked (sheared) 4th pipe and was tired of carbon monoxide in the cabin making be think I was flying. So, I got a new one from Lithia Toyota.

I was going to paint it with VHT (with ceramic) or Rust-Oleum inside and out but then decided to price having it done professionally. Jet-hot is $150 and Performance Coatings is $115. Now, I know that is almost doubling the price of the part, but is it worth the cost to never have the new part crack or break again or will a spray heat insulation coating do just as well for this engine? I don't know how much heat is generated by the exhaust manifold but it can't hurt to cut heat out as much as possible. It's a 1.6L 4AGE by the way.
