View Full Version : Who has wraped their header pipes??

I wraped my head pipe today on the 465 thumper with header wrap, what's the benifit, besids keeping the heat away from the cylinder, will a hot pipe work better? Sound waves travel faster the hotter the temps get, it seems like this would help the scavaging effect of the pipe.

I did mine. It keeps the heat from your header off the head of the motor. I personally have seen a great deal in drop in oil temp.
Its not a cheap mod. The wrap cost about a buck of foot.

If youd like to see a pic of mine, let me know. Dont private message me, I dont regularly check them. Respond here or contact me at KCowan@neo.rr.com.

Header wrap certainly works. Keeping the heat enery in the exhaust gas keeps the velocity up and it exits faster.

I'd like to see a pic. I think I will get my header chromed will this help keep the heat away from the head also, or is it just the wrap that helps.

Header wrap Chromed? Ive never heard of that before. It very well may help. If you find that it does, let us know.

How does it compare to ceramic coating?

Thanks to Rippin for posting my pic.

Most race motors do have ceramic coating. Back in the day when I took my car to the tracks, I was finding out all the other GN owners were going with the header wrap instead of the ceramic coating. I was told ceramic coating works, but not quite as good as the wrap. (the wrap is made of thick fiber glass):D

In case some of you motor heads wanted to know what my drag car looked like....this is me and the morning after. LOL

.....god, I loved that car.

What happened to your GN? I love those things. Fox Bodies and Grand Nationals were the only things to race in the 80s.

Six years ago, I was coming home from a bar and got hit head on by a drunk driver. Go figure huh.

I paid 9 grand for the car. My insurance company cut me a check for 14 grand. I didnt make out too bad though.:(

Your local speed shop, Jegs, Summit. Those are the ones I know of.

I went riding today, fifth gear, long winding straights, I couldn't feel any performance gains, as far as torque goes, there maybe a 1-2 mph gain at WOT.

i dont think wrapping your heading is going to give you a 1-2 mph gain

YEA ..OR NOT ....lol....i put my oil filter one backwards got 5hp out of it and then put nerfbars n and got another 5hp...lol

dont mess around by saying some of that stuff some people will try it. but if you want real perforrmace put sugar in ur gas tank.



DONT DO THAT!!!!!!!!!!!! I WAS JK LOL:blah

Yeah me either, but a hot pipe has to do something useful, wraping headers will work the best when in fifth gear WOT, when the exhaust valves are moving the fastest, a hotter pipe will scavang better, because the negative waves leaving the pipe will move faster. You might see a difference in the 1/4 mile drag, other than that, wraping headers won't do much for all around performance, but it keeps the heat off the cylinder, and that's a good thing for the engine.

That header wrap sure looks Fugly, i would rather get ceramic coating:rolleyes:

you also have to watch because you did not wrap the pipe correctly. you do not have the correct "OVERLAP" of wrap on the pipe. the wrap is supposed to overlap only a 1/4" inch or so. if it is wrapped unevenly it can cause hot spots and can cause cracking.

never happened to me but things i have heard/read

I dont see how you could really benefit from header wrap on a quad anyway.

Car racers use it for keep the under hood temps down so that the intake isnt sucking hot air. Since quads air boxes are in the back and they are pretty well ventilated I cant see how you would really benefit from it.

Sounds more like a waste of money IMO.

there are other advantages such as keeping the heat IN the pipe, which help with exhaust flow, hottor air flows faster

You maybe right there.. Im just saying is it really worth the money, and maybe even the risk (if its not done right and cracks the pipe) to mess with it.

Thats up to the person doing it I suppose.;)

HiPercoat from www.hpcoating.com does the same thing that header wrap does!! its coated inside and outside the pipe and it keeps the header cool and keeps the exhaust gas velocity up!!! And it looks awesome!!! You can have the header done for $45,,,,my header and midpipe cost $70!!!!

RED121572

Cracked header? Naaaa.

The 1/4 inch overlap is to ensure the wrap is doing its intended job of not letting the heat out.

I personally did not see any performance changes. What I did see is a drop in oil temp....and my right leg doesnt nearly as hot in the summer as it used to.

Personally i think header wrap is only good if you wanna make your quad look ugly. It just don;t look good.

Header wrap is not designed specifically to provide an instant gain in horsepower or instant results from your seat of the pants meter. Header wrap is more so for racers. Heat is a four-stroke motor's worst enemy, and the more heat there is, the more horsepower is lost. Where you would see the results from the wrap, or the coating, is in the final 10 minutes of a 30 minute moto, or towards mid-way into a gncc, where the engine is as hot as can be. When other four-strokes have lost hp due to the heat of the engine and the oil temp, you may have a 3-4 hp advantage on them, THATS where the results are. Your motor will run cooler, saving hp, and extending the life of your engine. Hope that helps. :D

Oh yea nacs, it is ugly, but it serves its purpose. The ceramic coating looks trick though.

I'm not talking about the chroming the header wrap, just the header. Should I get it chromed inside and out and what advantages will this have other than the look?

ChadEXer

You wouldnt want to get it chromed inside and out, but the HiPercoat from HP Coatings is real nice. It looks just like chrome except it is designed to do the same thing a header wrap does, hold the heat inside the pipe and keep the exhaust gas velocity up where your hot air is escaping from the silencer instead of heating the header up as well as everthying the header is connected to!!! The stuff looks awesome, its very affordable and it will do the same thing as that funky looking header wrap,,,cant beat that!!!

I think I'll go with chrome then because it will look sweet with a pced heatshield and it's free:D

You going to go with chrome or the HiPercoat??? Chrome looks good at first but wont for long! It will change colors on you! This stuff is guaranteed not to change colors!!!

Does that Hypercoat stuff rust? B/C I'm on my 2nd pipe from Curtis Sparks and my new one is rusting already. It's only 2 months old!!! WTF!! What a ****ty process Curtis uses!! The performance is awesome and the ceramic sucks!! Go figure. :grr :huh :confused:

Well i havent got a chance to run it yet but it is guaranteed not to rust or change colors or they will fix it for free!! Looks like some high quality stuff!!!
