Exhaust wrap

[xsbowes]

Anyone ever use exhaust wrap to cut down on the heat given off?

Yep. worked well until the pipe disintegrated almost 2 years later. The wrap holds moisture to the pipe and makes the pipe itself run hotter. I wrapped a set of exhaust headers and they turned to rust dust in less than 2 years. I wrapped a section of exhaust pipe farther down and when I unwrapped it it was noticably a lot rustier than the pipe on either side. :(

Your mileage may vary.

I had wraps on my 2.25 header for 5 years. They started to get a bit tattered and took them off. The header is just fine, but i do notice a lot more heat now that i dont have them on any more.

For the record, i didn't use the "wrap" i used this: http://www.thermotec.com/high-velocity-exhaust-jackets.html

worked great, no issues with the header what so ever.

I will be getting some in the semi near future.

Here is a picture of what i used, its not very good but you can see it under the intake.

Is that material Refrasil?

Not sure of the cost- and it would require removing and being without your headers for a bit..but I've heard good things about Jet Hot coating with regard to heat reduction. As a bonus you can have them coated in a finish similar to the intake- they'll look clean and won't rust.

I have thought about that too, i just need to find a place locally that can do it. I wont be driving it much this winter so thats an idea...

Bah! All these ideas are too fancy. I just chuck a bag of ice on the floorboard when the heat gets too intense. It's a trick I learned from a local guy. :cool:

Does the coating create other problems such as a loss of power?

Nope. They actually claim performance improvements- but I doubt it would be noticeable in a Rover. We'd probably benefit most from reduced heat in the engine compartment and increased longevity of the header. Here's the link for more info:

I would disagree, in a Series Rover the performance in crease would be through increased longevity of the driver!!

I wonder if putting this on the underside of the passenger compartment would be as effective as wrapping without the rust worries:

I painted my exhaust with high temp paint and was going to wrap it, however I'm not confident that would stop the rust for very long.
