What are the thoughts on wrapping your headers with a heat reduction tape?
I here some say to do it to protect other engine accessories from heat like starters etc, and to also keep the temperature under the hood lower to reduce your air intake temp. Others say not to do this because you want the heat to dissipate from the engine as much as possible and wrapping will hinder that.
It would seem to me that it would be more important to keep the engine from getting to hot, and if the starter or something is to close, try to make some type of heat shield. As far as the air intake, one can also work with some modifications to accomplish that.
Any thoughts, experience, or expertise appreciated. I'm installing Borla Headers, Gibson Catback, Diablo Chip, and modifying my K&N filtered stock intake next week.
Thanks,
I would only do it for a race application because it will void your warranty with most header manufacturers. In a daily driver, or any car that sees more than a climate controlled bubble, the wraps will trap moisture and rust the pipes, according to hedman (I think it was hedman).
I personally would not wrap headers because I can not see the condition of the pipes unless the wrap is removed, which would be a pain in the a$$ with mine.
Just my two cents worth. For a nickel I will tell about my entire day.
Summit and P.A.W., for two, sell heat shields for starters, which would likely be a good option for you. Since we're on the subject, I've heard (and believe) the same regarding header wrap reducing the life of headers. That said, would you see any reason why ceramic-coating a set of non-stainless steel headers might cause a shorter life span? Any experiences? It would seem to me that the coating may protect them from rusting out, although, it is said to drastically reduce underhood and surface temps (good write-up in last month's Car Craft magazine on this.....). That heat has to be absorbed somewhere..... does the ceramic coating take care of all of it? Or, does some get absorbed into the steel of the header and weaken it or otherwise reduce its life?
In my opinion, ceramic coatings should let headers live longer because the coating stays on once the engine is run for more than 10 seconds, unlike paint which burns off and smells bad while it does. The coating is a form of insulation that is similar to paint in that it adheres to the surface and keeps moisture and air off the protected surface, the two things needed for rust.
The inside of the pipes are subject to moisture and air all the time.
Correct me if i am wrong but for every gallon of gasoline that goes in an engine, a gallon of water comes out.
Another clue that ceramic coating is good for headers is the vast number of companies that do it and the fact that you can buy headers with a coating from the manufacturer.
Thanks for your comments..... I'm locked between a set of non-ceramic coated, stainless steel headers and ceramic coated, non-stainless steel. The ceramic coated would have their obvious benefits, though I'm wondering about their lasting power against the stainless steel. (The stainless would save some $$$). I could go all out and purchase the ceramic coated stainless version, but I've got to cap the price of this project somewhere.....
Ceramic coated headers will last longer than anything, even nickel plated steel (stainless), in fact, that Car Craft writeup says by at least 5 times longer.

Must have missed that..... (too many pretty pictures ). I'm there! Just needed something to sway me one way or the other. And, with all of the wonderful electromechanical gadgets that electronic ignition and EFI bring underneath the hood, any reduction in temperatures has got to be the way to go. I appreciate the responses!
i put headers on all my trucks.
painted headers last me 5 to 6 years.
your climate our driving habit will affect the life of the header.
I personally like headman.
ceramic coated headers are gaurented to last 5 years without turning color. you get what you pay fore
