High heat downpipe insulation
I was looking at insulation options to wrap my future downpipe I will build. I came across this >
http://www.mcmaster.com/#high-temper...lation/=ty5ti4 The "ultra high silica sleeving" rated at 2300 degrees THinking about slipping 2 feet of this "ultra high heat" insulation before welding the v-band. |
I had good results with DEI titanium.
No idea about those you linked. |
DEI Titanium is the stuff.

If you do end up trying the stuff from McMaster-Carr, please let us know how it turns out. |
In the past I have heard warning about using wrap as it can trap water and cause corrosion. What materials would you feel comfortable wrapping with the DEI titanium? Aluminum? Stainless? Mild steel?
|
My stuff is all stainless, no problems that I've noticed. Mine was wrapped before I got it, so I wrapped it, then I unwrapped it to add a wideband bung, and wrapped it again. No cracks, no corrosion.
I'll probably wrap my ARTech downpipe (also stainless) and not worry about it either. |
If you're wrapping it to reduce heat, then there's probably not an issue with moisture remaining. Its probably an issue for cars that aren't driven frequently or far.
I was looking at this stuff - wrapped and strapped with stainless zip ties. Much easier to install when the down pipe is in the car too.
