I've heard of people using header wrap on their header does anyone know what we could get from putting it on h22 exhaust manifolds?

 

but why?

i've never needed header wrap. if you want it, you can use it. but on a stock oem manifold, it won't do anything. and probably is a waste of money.

 

header wrap keeps heat in also...something to think about

I wraped my first DC header years ago... sold it to a friend who had it on his car for 5 years until a pack rat decided to eat it all. Worked fine, but not needed.

 

The heat wrap is designed to keep heat from disappating into the engine bay, and sometimes to keep moisture from making contact w/the head and thus preventing rust.

 

i just installed some headre wrap on my car last weekend. didn't make any power, but lowered engine bay temp a lot more than i was expecting. exhaust got a little louder i think though...maybe because the exhaust gasses are hotter and flowing faster??? plus for only $30 why wouldn't you give it a try?

I have been running exhaust wrap for 6 months on my stainless steel header. So far so good. I can't really compare between not haveing the wrap verses having it, since I wrapped it *before* I installed the header. You can take a look at it here:

I actually asked the guys here in the forum if I should have a heat shield or not, and well so far so good. No discoloration on the hood or anything.
One thing I have been told is that you should not put heat wrap on a ceramic coated header or cast. Wrapped cast will eventually rot.

Hope that helps.

 

If your header is cheap it opens up the door for cracking the weilds.
