I used header wrap on my exhaust and chose to change and go to Jet Hot brand ceramic coating. I have no data on how effective the wrap was at lowering temps under the cowl however, the issue I had was, the wrap draws or holds moisture and my exhaust was rusting badly.
I did some research and found a company called Jet Hot that specializes in ceramic coating exhausts for the racing industries. Steve Bennett of Great Plains recommenced them to me. I consider Steve Bennett of Great Plains Aircraft to be the greatest authority on the VW conversion and his recommendation was all I needed. You can find other ceramic coating companies but the difference is Jet Hot coats both the exterior and inside of the pipes. They give a lifetime warranty even on my not new pipes. After several years of use, I did have some questions on some spotting on my pipes and Jet Hot suggested I send them back. Jet Hot recoated my exhaust pipes without any hassles, or questions. In fact, I can not make a higher recommendation. I had the chrome like finish done to mine and they are beautiful as well as functional. I noticed a difference immediately. Jet Hot coated pipes scavage the heat away from the engine and I got an extra 200 rpm and noticeable increase in power and thats why Jet Hot is so well known in the racing industries. It will cost more then wrap but, you will never have to worry about your exhaust rusting and the long term savings as well as the lower temps are worth it.
