Took me awhile to get pictures but finally did. So I wrap pipes with 3 layers, the first one is pretty thick, second is about half the size, and the last is aluminized wrap which only comes in a roll or sheet and cut to 2" strips. You can order the sheets from companies like www.jegs.com or similar.



So first, you lay the first piece and as you go around, overlap it so it holds. You want to try and get it tight so it doesnt begin to twist on you. I use .032" safety wire to hold it as i wrap the rest. As you wrap it, you dont have to be crazy tight with it since you'll do that later. When you get to the end of the pipe, go back to where you started and able a firm hold around the wrap and twist to make it tight. I found that is the simplest way and it wont tear the wrap. About every 6 inches, wrap a piece of safety wire to give it more strenght to stay together.

The second wrap is really not needed but since I work on turbo'd engines, its a must to keep heat in so the turbo is more efficient. Its wraped the same direction as the first layer and in the same manner.

The final is used for appearance and to keep the heat from radiating. It also serves the purpose to keep heat in. Its more difficult to wrap this one and you do want to take more time wrapping this as it will determine the looks and if it stays together.

To apply this, cut 2" width strips from the entire lenght of the sheet. Next, you fold the end over about 1/8" and the lenght about the same. The reason for this is it keeps it from fraying. As you begin, the folded end faces outward of the dirrection that you are going while keeping the the rest of it fold as well. This material you cant twist it to make tighter so as you go around, apply pressure to ensure its getting applied tightly. When you come to the end, fold it over and safety wire. You also want to safety every 6 inches on this. By the time you are done with one pipe, your hands will feel like you just jerked of a donkey, so I suggest go take a break in between wraps. Hope this write helps but if anything is unclear, feel free to maessage me any questions.

Has anyone ever recorded any performance changes tnat are brought on by pipe lagging?
I know the principles behind it, but does it really make a difference to power and / or noise?
My engine runs cooler on hot days, but now my ass burns faster because the pipe goes right under my ass. but no performance gains that I can feel. I noticed that it smells when it rains

For automobiles, yes. For motorcycles, no.

Header wrapping for automobiles lowers the under the hood temperatures and allows for cooler, denser air to get to the intake/combustion chamber.

For motorcycles, it may lower temperatures a little, but for the most part, wrapping the header is for aesthetics.

Yup, tip to anybody doing this mod:
Wear as much clothing as possible! Yes, long sleeves in the summer, hat, pants, boots, etc etc etc. The fiberglass will have it's way with you, the least you can do is limit what parts of your body.

I didn't try wrapping it wet, good idea, I just went slow and steady, pulling taught after each wrap.

The wrapping cooked off all kinds of nasty fumes and smoke for the fist couple of weeks for me. Be aware, I was choking out cagers at the stop lights who thought my bike was on fire for a couple of weeks.

I read about performance gains and thought it couldn't hurt but between you and me I was mostly covering up my rusty ass pipes.:dancingmonkey:

would wrapping it wet be likely to cause rust or corrosion???
