So, I just finished a big article in the performance tech forum about the importance of header wrap, if you don't believe me, or understand, go read it. But I also promised a DIY on how to, in case it was scaring anyone 
, so here goes.
Materials needed:
50' header wrap
Stapler
2 3" diameter worm drive (hose) clamps
Gloves
1.) Purchase header wrap. I bought mine at Alamo Motorsports for $35 shipped. The 1" by 50' roll (part # 11001) is plenty for most headers. Here is the link to the wrap. Click here.
2.) First, wear gloves when handling, it is like fiberglass and will irritate your skin. Remove and cut off about 10'. I wrapped my Megan Header for an F22, this was about how much each runner required.
3.) The package said to moisten (not soak) in water to make it easier to work with, I didn't and had no problems.
4.) Start at the top (cylinder head) end of the first runner. Make one complete loop with the wrap, and pull it. Use one hand to hold that loop in place, you will need to keep holding until the wrap develops enough friction it won't spin.
5.) Continue to wrap down the header. Be sure to pull very tight as you go. I overlapped about 1/8" and it worked great.
6.) When you reach the bottom of the runner, continue to hold with one hand, while with the other hand, staple the loose end of the wrap onto itself. This is a temporary hold till the clamp is attached.
7.) Repeat 4-6 for the second runner.
8.) At this point cut about two feet of wrap and overlap both the runners and continue down to the flange (I wrapped a 4-2-1 header, if doing a 4-1, wrap all four runners before doing this step). Then open the worm drive clamp all the way, and secure it at the bottom of the wrap, so it holds it all in place and make sure its tight.
9.) Repeat 4-8 for the second set of runners.
There you go, your wrapped and ready to be efficient. I performed this with the header out of the car, it could be done in car, but will be more difficult. It took my about 30 minutes.
The header wrap will smoke for the first ten minutes or so, don't worry, it's curing. Once cured, it will be a nice silvery color and hold in place fairly well on its own. Thermo-Tec also makes snap clamps for the wrap, but I didn't feel like spending the money.
Good luck!!
