Header wrap
 

Should I wrap my new dynatech headers with an exhaust wrap? I assume since they're stainless steel they'll be giving off a ton of heat.

I don't see where it would hurt at all. The header wrap does a good job keeping the heat in.

Coat them with one can per header with VHT ultra high temp ceramic header paint. then wrap them with the 2" wrap. be careful to overlap it 1", this doubles the thickness of the wrap and is VERY effective at reducing under hood temps.
I used a industrial Heat gun to bake each primary as I coated mine.

After a couple WOT free way runs, I can pop hood and grab a header primary. yes its hot as fook, but I don't burn myself.

I probably won't paint them and just stick to wrapping them. I already have high iats so I figure headers will definitely make it worse so I'll probably get some wrap here soon.

I agree with ezdaar. If you get 2" wrap, overlap by 1".

I wouldn't wrap or coat them at all personally. The stainless turns a beautiful color once heat cycled and gives a great look. Yes, engine bay temps will be higher than stock, but if you have a proper CAI which seals off from the engine bay it shouldn't have any effect.

That's the problem, I have the same k&n that dad installed in 2003 when he bought the truck before people sealed them very well.

Wrap from the rear of the header to the front. That way the overlap is facing rearward and air flowing across the headers doing down the road doesn't try to lift the leading edge and make the wrap start to fray on the edges.

So assuming I buy the 2" and do the 1" overlap, how much do I need? Also what brand and where do I get it?

I was going to remove and replace my header bolts today, and the first bolt I touched broke off with no pressure even applied yet. This is going to be a looooooong day
