Before & After exhaust wrap?
Anyone have real temps/dyno/spool up results?
Also, how much of the cross over should be wrapped?
I read that if you wrap parts that have already been ceramic coated, the coating will turn to ash in a few months??? Anyone heard that???

Semi-related question. I have about 40ft of DEI exhaust wrap leftover from when I did my truck. Where is the best place to use this on a stock turbo setup? Work from the turbo back the cross-over or from the header towards the turbo or somewhere else? I'm not sure 40ft is enough to do everything. I just want to use it up.

OK, thanks Derek.
Mike, I would say do as much of the headers as you can as this will keep temps up in them pLUS help to keep temps down in the engine bay. Start from the front and work your way back.

Found this one example:
"I used an IR thermometer and recorded temps that hovered around 190F on the bare exhaust.
After installing the wrap, I took an approx 40 mile r/t drive to get a reading (and to get out of house for a bit). Two interesting things came from my drive...
1. the exhaust wrap puts out a very unique smell - almost like warm apple pie
2. the exhaust temp reading after installing the wrap ~265F"
So is that proof of keeping exhaust heat in the pipes and temps up inside?
However, I keep finding statements:
"if you wrap your exhaust/headers their lifetime will be reduced considerably"
Anyone???

Example:
"Quote:
Q: Why should I not use header wrap?
A: Wrapping headers should NEVER be done. Wrapping headers will destroy them and there is no header manufacturer that will warranty a wrapped header. The heat wrap will trap moisture or condensation between the header and wrapping causing it to rust. Heat wrap can also destroy any Ceramic Coating. The best way to keep anything from the heat is to wrap the part you want cooler, like starters or fuel lines. Another way is to have them "ceramic" coated. "

After the wrap on my car caught on fire...I wouldn't put exhaust wrap on my car again if you paid for it and put it on for me. Any leak at all, anywhere on the engine is going to get down and blow onto the cross over pipe...where it will soak into that wrap and stay there....until there is enough to ignite..and that takes less than you think.
Ceramic is for exhaust.

Last year during a DE event I had a coolant hose at the back of the engine
go. It sprayed coolant onto the header which was wrapped. After the car was shut off and I was trying to find the leak, the wrap ignited.
Scarred the sh..t out of me.
Luckily I had an fire extiguisher handy.

OK, now I gotta send my wrap I bought back? Not sure i have the reciept.
What if it is the Copper style wrap and/or you spray it with the thermal coating to keep from being able to get soaked?
