I was wonderinf if anyone has had any experience with the Exhaust Wrap insulation that you can wrap your downpipe with. Is this stuff a good enough heat shield?

This stuff---- http://www.designengineering.com/pro...asp?m=sc&cid=3

 

I'd be interested to find out if people used this to wrap downpipes. and if they had any adverse effects like pipe rusting, etc
i know I used to used it back then to wrap my v8 headers and it did keep temperatures lower under the hood. But they say that the piping will rust sooner.

 

Just have it jet coated

 

Jet Coating requires my downpipe to be off for a week and costs roughly 4 times what this stuff does. It does look sexy though

 

inconel downpipe

 

I wrapped my downpipe when my hatch was turbo charged. It does the job very well. No rust as the pipe was hot enough to evap it quickly but I could also touch my downpipe after some hard runs. It is worth its weight in gold!!!!!

 

I've wrapped a DP in the DEI stuff before. It's fiberglass, so wear gloves when dealing with it. Hose clamps work best at keeping it attached.

If the DP is stainless I wouldn't worry to much with it rusting, a coated mild steel DP is going to have the coating cooked off eventually, and then rust.

 

Well, I'm sold! Thursday's project- remove downpipe and wrap it! I might add a silicone coating also to keep it fresh looking. I'll post pics if I get my camera back.
