I did a double wrap on the up pipe and cross over.
If I remember right two rolls of two inch did that, and I had a bit left so it went on the down pipe.
Started at the top and went down till I ran out.
5 rattle cans of paint between the three places.

When you say "high temperature paint" are you referring to 2,000* F header paint or the more common 1,200* - 1,600* F stove-brite or similar paint? I bought some of the 2K stuff to spruce up the turbine housing on my Banks during the rebuild... thinking of getting a bunch more and some wrap, but maybe 2K paint is overkill???

i used this kit:
Design Engineering DEI 010110 - DEI Exhaust Wrap Kits - Overview - SummitRacing.com
not sure what everyone was doing with so much paint.you can only coat the thing so much.
1 can was enough to coat the pipe,one layer of wrap,and then the top.an extra can wouldn't of hurt though.
it's the wrap that does the work holding heat.
two 50' rolls of 2" was enough to get a nice overlap and cover everything pretty good.
there was enough to get two layers on the up and downpipe,but just enough left for 1 layer on the cross over.
so if someone is doing this,plan on 150' of 2" wrap to cover it all with 2 layers.
the cross over is easy to get to,or heck,just take off and add a wrap and put 'er back on latter.so do that one last.
now if only there was a way to wrap the exhaust manifolds while still in the truck........

The way it was explained to me was that the paint is used to seal the wrap against moisture absorption. The same with painting the pipe first. It's to keep the moisture from the pipe if it should get into the wrap and not dry out. Thats what will degrade the pipes. Seems like you could let the truck run for a while after driving in rain to dry the wrap out..

you never splashed some water on a 800 degree hot surface? what happens to the moisture in a few seconds?
iv no worries about pipes rusting out due to moisture.besides,a few pipes are replaceable.performance and efficiency are not.

I've read a number of times were more often than not the pipes rotted out. they look good with the wrap on them and then they take the wrap off and the pipes are swish cheese. i would wrap my pipes if somebody could of me some conclusive evidence that everything will be fine. especially since i have my turbo off right now.

well exhaust rots out.they don't last forever unless you go stainless steel.what kind of time frame were they talking about? was it 1 year or 10 or more when they claimed swish cheese exhaust pipes,and how did the rest of the unwrapped pipe of the same age seem to fair in comparison?

I personally had two trucks that had the turbo up pipes wrapped for a long period of time. When I took the wrap off, the pipes were pretty much shot, corrosion destroyed them. I think the heat retention of the wrap also does something along side of the moisture.
Granted, this was after like 5+ years of being wrapped, but the wrap will destroy the pipes eventually. There is a reason that every header manufacturer will VOID THE WARRANTY if you wrap them.
It does however make a drastic differance, and I believe is TOTALLY WORTH IT.
I think ceramic coating would be the best option though. A local guy around here qouted me 100 bucks to do the pipes on a hypermax system which isnt bad at all. This would make the pipes last twice as long...

ah 5 yrs is good.if im lucky the truck will last long enough before it rots out inside of 2-3 pipe replacements.
nothing lasts forever.
maybe we better order a couple 3'' dp's from banks to keep 'em on hand.the up pipe is cast,so that'll be ok.the cross overs any shop can bend up even if banks one day stops all production for idi's.im sure a shop could bend up a dp too anyway though?
