Just curious, anyone know if wrapping the exhaust would reduce temps too?
I did and it does help for sure. I don't know if it lowers engine temps at all, but air temps around the exaust drop noticably.

Put an EGT probe in the tailpipe and tell me what you see then
Ok. Why? Were talking about headers and engine bay temps.

On a related note, bra sizes are increasing in China as diet improves due to an emerging middle class.

How many of you have had your manifolds coated? Any noticeable gains etc?
I had a exhaust header for my 2.25 petrol ceramic coated by Jet Hot Coating about 17 years ago. I did it to prevent rust though. And to hopefully keep a little heat away from my alternator and starter.
It's rusted some so I guess I could send it back to be redone, to see how their lifetime warranty is.
I wrapped my headers in my old turbo miata, and it helped a great deal. I'm sure the same would be true for the Defender.
The guy asked about wrapping the exhaust, did you assume he was talking about wrapping the cast iron manifolds?
No, why would we be talking about that in this thread? We are all clearly talking about wrapping the tail-pipe, to lower the temperatures behind your car as you drive. Nobody cares about lower temperatures in the engine bay.

Although, I did continue mine further back to keep the exaust temps from warping my skid plate. Of course, I didn't need to do that because diesels don't generate any heat. Especially not enough to ever warp plastic.

My Tdi Exhaust gets hotter then an Asian woman with a D-cup especially under my feet in the summer. I am going to try the wrap..
No it doesn't. You can lick it while at speed on the freeway. :tounge

That said, you will find that the wrap makes a big difference in temps near the exaust.

lol.... good link. im trying it:)
Ebay has it for $45 shipped with the little ss ties.

I used the stuff from Vatozone and it was $50 with no ties.

Cheers

Garth wrote I am still not convinced that wrapping headers doesn't accelerate their deterioration, though.

I with Garth on that one. Buck may know of Ed Hansen (great exhaust guy) in Spring Valley. He recommended NOT to wrap the manifolds due to accelerated deterioration. I did wrap the before and aft the converter on the Y pipe to try to keep the temperature down in the cab as it gets way hot on the feet in the summer.

Not really answering the question on engine bay temps as I did not take a before and after temp check on the engine bay prior to instaling the ceramic coated header install.
It may or sure, and it may not. I have heard it may lead to cracking, and heard that it may not. Nobody knows for sure. The only thing that is for sure in this life is that us driving these trucks is directly killing polar bears.
