headers and header wrap Options

[twitchh17]

for those of you who have headers on your GT's and ST's how many times did you wrap the header wrap in one spot? once or twice? would there be any difference wrapping it around the same area twice? thoughts and opinions will be appreciated.

just follow the directions on the package. i overlapped my wrap by 1/2 width on each turn.

wait was is this wrap u guys are tlakin a bout?

Heatwrap, I suspect. It's used to keep your exhaustheader from radiating heat.

heatwrap is bad, especially on those cheap ebay headers.
it will hold in condensation, and make them rot MUCH faster.

i accidently peeled some of my wrap back during an oil change, the stainless under it looks just fine. i've had my wrapped for just over a year of chicago weather, which is not easy on cars. i think as long as its REAL stainless the wrap is OK.

it will rot from the inside out.

well, based on what you're writing, i guess you don't suggest to wrap the headers, right?

i dont see how? there will be condensation in the inside no matter what when the car is off and the steel cools off, just a matter of how fast the steel cools off. it being stainless with a good coat of carbon soot, i cant picture it corroding very much or very fast on the inside, especially since it gets dried out atleast once a day at several hundred degrees for several minutes. if anything, the only issue you may run into with the stainless and wrap would be annealing the metal or welds over time, but doubt that would be a big problem since the exhaust system is well supported by the hangers on it. seriously, a real stainless header will not corrode due to wrap. its the chromed or mild steel ones that do that.

eh, thermal paint it. If I wrap mine I would probably check it often. Some have problems, some people don't...

ive had my headers wrapped for the last 2 years. It does a good job but i needed them wrapped. The amount of heat that comes off them *even with ceramic paint on it* still makes my window fog up if its below about 10 degrees celcius. I wrapped mine about 1/4 overlay every time around. But with heatwrap, be ready to wrap them again every so often. My header wrap is starting to get really brittle and is starting to fall apart now. I use the DEI stuff, but i think in the spring im either gonna go get the headers heatcoated if i decide to keep it on the car.
