i bought some semi new dc headers of craiglist but the problem is that i cant find any headers wrap whats the name of the actually product and do i need some and also do u have any ideas if it will sound nice on a f22 automatic!?

Try Pep boys. I heard they have a good brand for $30 a roll. -
I just put some DC's on my a4 auto. I already had a dynomax cat-back, and that only sounded good (IMO) between 2700-4000 rpm. Now with the DC's on, its growls at pretty much any rpm, but not an annoying fart can sound. I absolutely love it!
Also, we just painted mine, but now that it's done it yellowed and we completely followed the curing instructions. just be careful, if it's semi-new, it might have some weak welds and header wrap can shorten those weld's lifespan (esp if it's ceramic coated)...BUT i personally think wrap is better because it reduces temps by a ton more, plus I think it looks great! At the very least, if the paint on it is in bad condition, at least strip it, sand it, and apply a high temp primer to prevent rust.

If it's ceramic coated dont wrap it. It will crack sooner rather then later!Comment

Headers? So you'll install one... what will you do with the rest? (I'm being a smartass... it's an inline 4, you only have one header.)
It's a header. Just like yours. What do you need pictures for?Originally posted by supremacycc View Post
Agreed. It's mild steel, and should already have that thermal ceramic coating. Wrapping your header is not necessary. It decreases engine bay temps, and can increase exhaust flow velocity by keeping the heat in... but it's hard on the metal, especially the welds.Originally posted by ATS666 View Post
As for the sound... that will depend partially on the rest of your exhaust system.

if your header is a real DC header then it should be ceramic coated.

You never NEED to wrap a header (and again, it's only ONE header... no "them")

okay sorry but i heard that with the heat it will start melting whatever its close to it>Comment

Does your stock manifold melt everything close to it?
Rather than planning your shopping list based on what you heard... it'd be smart to actually understand what you're doing with each part, and why.

the stock have a heat shield and the aftermarket will not ?Comment

That heat shield is nothing but a sheet of metal. How much heat do you really think it shields?
