Header wrap?
Is it worth it?
Not trying to achieve higher exhaust temps, just have a roll lying around, and, it would be nice to get rid of the silly exhaust manifold cover.
Thanks!

It sure makes the engine bay cooler. I haven't messed with it on my miata, but on my rx7 with its sky-high EGT's it's a must, along with a turbo blanket. It pretty much ignited EVERYTHING within 6-10 inches of the turbo. After wrap, I can touch it, bare-handed.
Use hi-temp silicone spray-on sealant, helps keep water out of Yo Wrapz

Do it, but don't go too far down on the dp if it is a dd because it will hold moisture and could eventually cause flaking...and it is a waste of wrap out of the engine bay. Soaking is a must before wrapping along with metal straps (or could use hose clamps). I got the black stuff and it has lost all color from changes in temp.

I think it does not matter what metal it is. Wrap holds so much heat, that components do not last as long compared to unwraped. I had cracks in my header that I had to have fixed because of the long term use of wrap. I have heard others with mild steal exhaust components complain about this problem as well
I still think the benefits of wrap are worthwile however.

ok this is maybe a little off topic, but what about ceramic coating it compared to the fiberglass wrap? i was thinking of jet hot once i heat cycle my manifold a litte. any thoughts? i would think there would be as much concern with cracking and it wont keep in moisture being its powder coated on

I did ceramic coating, then header wrap, then silicone sealant spray. This is supposed to protect the stainless from corrosion and fatigue. It also does a really great job keeping the heat inside the pipe and out of the bay. I am quite happy with the results so far. I had a mild steel set of headers on my Camaro that were done the same and lasted better than 10 years. They saw tremendous heat from lots of bigblock on the bottle.
