Be warned that the tubular manifolds on the Series 1 cars, as well as some headers have been known to crack due to header wrap in the past.

DrJay has more information on this. I have header wrap here, but have delayed installing it until I know more about the cracking problem.

After 6-12 months it breaks down, and becomes worthless. I believe header wrap voids ALL warantees on custom headers. Ceramic Coating and header wrap can easily **** up a good set of headers. Like Bill mentioned, it can crack your headers due to the excessive heat. So you must be aware of that, if you were to grab a set of $600 headers.. that'd **** me off if I blew those.

That'* the same here - I've had a nice big roll sitting here for well over a year, but after hearing about it trapping moisture and cracking the pipes I'm kinda hesitant. I would be so much if I knew that sometime in the next few months I was going to either order headers or new mani'*, but it seems if I'm doing something I'm doing it right now, unless something like this comes up -I wish I'd looked into the negative effects of this before I spent $50 on it.

Ceramic coating does the same as header wrap. I was talking to my dad about coating my headers, and he said I should avoid it because like header wrap, it is prone to damaging the headers. He also mentioned he had a friend with a '72 El Camino with a 428 who got his headers [aftermarket] ceramic coated, and after a few track passes they cracked.

Header wrap keeps more heat in than the coating and it also keeps moisture on the metal which accelerates deteroration(if the wrap isn't coated with a sealant). When headers come from the manufacturer ceramic coated with a warranty, I can't really see it being the same as wrap.

I have wrapped my crossover pipe for my TOG headers. It helps keep the heat in the pipe, and by extension maintains velocity, as well as keeping some of the radiant heat away from my throttle body.

I have never seen any evidence of moisture accumulation. Besides, if ever there were a problem I could simply replace the crossover.

As for wrapping the headers completey, that'* not something I intend to do. Otherwise, getting the headers ceramic coated seems the wisest choice. As both the SLP and TOG headers are made from stainless steel, they seem to be good quality and I haven't heard of any cracking problems with any high temperature coatings.

Cheers,

Most aftermarket header companies will not honor a warranty if they find evidence of header wrap. I have personally NOT seen any cracked headers from this, but have heard of it.

Sorry quick question.
Is the TOG DP stainless too?
