Has anyone used this stuff? I was thinking of getting a few sheets and putting them in the area by the firewall where the sidepipes exit under the car and maybe wrapping the pipes from that area down to the collector on the side. It gets fairly hot in the car and I don't have ac. I will also add under carpet heat/sound insulation as some point as well.
Yes it's nice stuff. I little pricey but nice. Much easier to work with with the pipes off the car but it can be done on. Here is my post on this: https://www.corvetteforum.com/forums...-opinions.html So far so good. It definitely does help with temperatures. Try to get it good and tight and use lots of the little clamps. They can be a pain, think about getting the tool to tighten them. Worst case you could use regular worm drive clamps if you can't see them. And I don't drive my car in the rain so I'm not worried about all that stuff getting wet, not that it wouldn't dry out but...
OK I see now you are talking about using 'sheets' which I have no experience with (should have read your question better lol). DEI has a lot of products for this so possibly they have an adhesive backed sheet, not sure though...
I saw that they have a few different adhesive back sheets, the difference being the temperature each sheet can handle as far I could tell. Any idea how hot that area gets? I don't drive my car in the rain either so I'm not really worried about rust/corrosion. But it would be nice if by adding a couple of heat sheets and wrapping portions of the headers/exhaust I could bring down in cabin tempss.

Any thoughts or suggestions?
There is an older post where someone tried multiple ways to block heat from the cabin including putting mat on the firewall or floor boards, it didnt work. The best results came from venting the hood or wrapping the headers. I bought some cheaper stuff to wrap my headers with a friend wrapped his entire hotside of his turbo setup to keep under hood temps down and it works.

Very informative thread, thanks! Does that reflectix tape actually work? I'm not really trying to block the sound since the side pipes are LOUD. But do you think that if I removed the carpet and then laid down a layer of the reflectix tape and then put dynamat or fatmat on top of that, it would help to keep the heat out?

Refletix is insulation, the tape is needed to seal the pieces together or hold it down if taped to the car.

Oh okay. So the reflectix tape holds down the pieces of reflectix insulation to the car. Would that be sufficient for keeping out heat or would I still need to add something over top?

Some people claim great results with relectix and some have moderate results.. I think it depends on how hot your car is getting.. I have it in my car and still see 109+ temp at the gas pedal after driving for an hour.
Look at this website. HERE . I have used some of their sleeving. The zero clearance product is very good also and the prices are pretty good compared to other products. I have used Reflectix in the tunnel before on a friends car and it made a big difference in reducing heat in the cabin.
I doubled down and did thermotec on the inside (basically relectix) over the tunnel area, dynamat on the floors with jute backed carpet, and then the stock insul-blanket in the tunnel and DEI floor shield where the exhaust goes through. I'm also a supproter of the foam collar to keep some heat from flowing right into the tunnel
The inside and tunnel/collar was done two years ago and I added the DEI sheets last year, each made a noticeable difference

I had my old block hugger headers, completely wrapped in DEI and really, it didn't do much. Here's the problem I had. The block hugger headers on my SBC ran within a 1/2 inch of the steering box. That's what is heating up your steering column. I tried everything and what has seemed to solve it (so far) is the block hugger headers from Sanderson that are coated both inside and outside. My steering column does not get to 160 degrees anymore and is only warm to the touch, not hot. In fact, the Sanderson headers are even closer to the steering box and are only 1/4" away, but they are running cooler. So far so good. I'm going to be driving tomorrow as I just installed these a couple of months ago and it's going to hot out here and report the results.
I have never liked the idea of using Reflectix in a car. I don't think it's intended for that use, it's just a lightweight plastic/foil bubble wrap and won't hold up to any type of wear in area like the footwell. Something like dynaliner is better for that - much more durable. Just my .02.
