Downpipe Heat Tape Vs. Blanket

[79GLIDE]

Have we come to a consensus regarding the use of heat tape on the downpipe vs. commonly used blanket material?

I'm not sure on this one. I'm planning to use header wrap on mine. Then I'll have a universal blanket covering the top of the wiring and cables for added insurance.

Ceramic coating. If you are in a area that seas a lot of road salt, wrap can hold moisture.

Third choice is a heat sleeve made by Donaldson that comes in 12, 18 and 24” lengths. Can’t come unwrapped.

Thanks for the responses. Was mostly curious to know if heat wrap provided enough exhaust flow benefit to make it worth wrapping. I've got a roll in my shop and considered wrapping the down pipe while I've got the heads off for head gaskets.

I’m doing it just for reduced heat on the firewall. Also possibly less in cab noise.

Me too.

Are you guys covering the up pipe too?

I used wrap on my banks downpipe and my uppipes still had good aluminum factory wrap on them, so I left those on.

The back half of the downpipe on my '93 has the aluminum on it, and that's it on the pipes. The PO put the rest over the AC box.

Up pipe, down pipe and crossover are wrapped and sprayed. Blanket on the turbo as well. if you're able, I'd suggest that you replace the restrictive stock downpipe while you're in there.

I've got the wrap and the spray. What are you running for your downpipe?

I have the banks on the '90 and a Diamond eye that was from the OBS powerstroke kit on the '94. Both needed work to fit, but the banks does bolt up to the turbo, just needs to be mated to whatever you are running for an exhaust system. Do a search, lots of information on the different down pipe arrangements...
