Hey y'all,

I'm wondering if anyone has any experience or input on using exhaust wrap instead of manifold covers for my new engine setup. Seems like it is hard to source a good set of covers, and the wrap comes in green! But I've read stuff online that wrap can make the exhaust too hot, cause a lean mixture and engine failure, or headers from cracking because of the heat. This may only apply in race applications and not in my family sedan car, but has anyone ever done it?

As far as I know, and have seen on TV, the wrap does not cause engine failure. Sooo many wrapped manifolds out there. Just soak it before you wrap it on.

You know, Matt, I was going to reply and forgot, but I guess I am wondering what header wrap will look like on our manifolds. They won't be easy to wrap, and the stuff isn't good looking in any way.

If you want to have nice looking manifolds, I'd suggest getting a set jet-hot coated. That stuff looks great.

That said, those problems you've described there seem like pretty far-fetched problems.
I am active in the classic car world where exhaust wrap is used more often and I've never heard of any of that stuff.

I wrapped mine. It was a pain and impossible to get complete coverage.

Is it possible to wrap them while they're still on the engine?

Why?

What was the expected benefit?
Less heat?

I broke the crap OEM tin shields getting them off the car. Seemed easier to wrap them a bit than to try to rescue another set of shields. Plus now there's more room to work. No expected benifet, just easier. I wouldn't do it unless I was swapping heads or manifolds anyway.

I understand - I had forgotten entirely about those shields. Thanks Nate.

I briefly considered wrapping mine when I had to bust the upper passenger shield to get that manifold off. In seeing how buried the driver manifold is, I elected to bend the shield back into shape and use stainless washers and a salvage yard bolt in better shape to reinstall the shield.

I wouldn't try it in the car, would be a nightmare.

Thats the logic behind it for me. Stephan is putting the final touches on my new engine and manifold shields are hard to source that arnt rusted beyond the point of install. the wrap seems like an easier option, more room in the engine bay, and I can colour match them to my theme. So all in all, seems like an ok idea right guys?

i haven't had any issues with several thousand miles on the car, and the extra space is nice.

I don't even have upper shields on mine at all... Been fine for going on 3 years....
