Wear gloves when u cut them because there is fiberglass in the wrap. Hurts like hell when it get into your skin. Buy long rolls and make sure u wrap them tight. I used radiator hose clamps to hold them down.

I've wrapped 2 headers, one on my RS and just recently on my L. First and foremost it makes things much easier when these items are off the vehicle. Second, the fabric used has particles that get airbourne, I suggest wrapping in a well ventilated area and wear a mask or you'll be blowing crap outta yer nose for several hours after the finished product.

DEI makes a good product: http://designengineering.com/products.asp?m=sp&pid=9

Heat Shield does as well: http://www.heatshieldproducts.com/insulation_index.php

I have only used the 2" rolls, they take some time to wrap well, making sure you cover all areas. When wrapping, constantly pull the roll tight to ensure good contact with the exhaust parts to eliminate any folds. Also purchase the stainless steel fasteners, the header will be the most difficult, I suggest you start with the uppipe and DP to practice. Its good to start right up to a flange (using a steel fastener to secure your starting point) and work your way through the item, you'll figure it out pretty quickly.

Look at how they wrapped this to get an idea: http://designengineering.com/products.asp?m=sp&pid=12

When complete and installed, for several days to a week the exhaust wrap will emit a scent from it burning solid onto the item, sometimes you'll get this smoke scent into your cabin if you run heat pulling air from outside the vehicle. You may want to set the control to recirculate instead.

Any other Q's, lettuce know

last but not least, soak the wrap in water for 5-10 mins, this allows you to pull the wrap extremely tight around the header/uppipe/downpipe.

I tried with it dry and it felt like a huge sock, once soaked, i was able to minuplaite the wrap anyway i wanted.

yes this will cause slightly more odor/steam from the engine, but within the week or two it will be gone.

Highly suggest you do this. It will also cut down on the flying particles a lot. It will also help tighten the wrap around the header even more as it dries.

Also, ditto on the gloves.

Last it get a can of silicon header wrap spray. spray the wrapped header real well ; it will keep the wrap from soaking up water and oil; the latter being a potential fire hazard.

I'll be getting a fire extinguisher, too.
No, not in a ricey visible place, either

Also.. wouldn't spraying a sopping wet piece of exhaust with silicone make it hold all that water??

That's why you wait for it to dry a day driving it around should do (hopefully on a sunny day)

ted coated headers tend to go through 02 sensors. if ya need a hand give me a shout i have wrapped serveral headers. if ya do it yourself wet the wrap after ya get the length ya need it will glue itself together. after all has dried spray the wrap with dei header wrap paint . it seals the header,and protects it from getting water damage.

Wrapping exhaust is nice, but considering your luck..... it only takes 1 drop of oil to destory a whole car.

Coated headers are less likely to blow thru an O2 sensor then a stainless unit. A Coated and Wrapped header is going to respond fast and hold a lot of heat in. Then agian i'm not a level where i even need a header, stock cast iron while very heavy works great.

Who are you using to coat your headers?
I've been through more than a few variations on coated pipes and not had the O2 sensor fail due to the coating on the pipes.

I've seen O2 sensors fail due to over rich conditions, leaded gasoline, burning oil, too much antisieze on the O2 sensor threads, and even who knows why it failed the car was stock!

O2 sensor failure from ceramic coated headers is news to me.

Or I could leave them unwrapped and just not worry about it?

Or get them coated? Where the hell can I get them coated quickly?

Loko Coatings, andrew has their information, IIRC it's a 2 day turn around and they are local.

It happened to Masuo a couple years ago. But it was from a poor coating on the inside of the header that burned off and fried the sensor.

I think the header mfr. (or vendor) ended up paying for his O2 sensor, as it was a bad batch of headers.

Make sure to get a neon "APC" one, they work the best. Royal magenta is a terrific color. You should wire it to detonate off of the unused NOS switches you have. Also, make sure to use the highest quality alumnium foil that money can buy. I'd suggest 7 rolls of Reynold's foil. You should buy it at Dominick's. Don't forget to get the widest rubber bands you can find to attach it all.

IIRC, chewing the foil is a great way to prep it before you wrap the exhaust.

i have wrapped the gruppe-s headders and my DP. definately soak them and i used 1 50' roll for the dp and 2 50' for the headders. use the dei exhaust clamps they are HIGH TEMP. also use the silicone spray to protect it. after wrapped wet as munc as possible. stick it in the oven at about 150 degrees for about 10-20 min then turn it up to 300 degrees for about 10-20 min. after on your car let it idle for about 10-20 and then let it cool down and you should be good. if you have any questions feel free to PM me.

Wow, nice wrap job. Looks neat.
Hi Flitz.. Didn't know Masuo went through some problems with his headers. Any idea who did the coating?

I guess I should post some pics too eh?

all good suggestions listed here.

they are almost all the things i did when i wrapped my header almost 4 years ago...but now my wrap has fallen apart- literally. it started disintegrating and chunks would fall off.

-header was jet-hot 2000 coated...and yes, i went through an O2 sensor.
-i wet the wrap
-dried it off after it was on
-coated the wrap with the high temp spray
-used metal clamps to secure the wrap (this might be the whole problem...these fell apart)

if i had to do it again...i probably wouldnt wrap over the coating.

Header wrap doesn't last forever. I think 2-3 years is the expected lifespan for a car driven year-round, even with the spray.


BTW...I went through 2 75 foot rolls when I did header, uppipe, and downpipe.
