Unless your running a ***** out race bike all these tweaky thing's don't mean squat but bragging rights over a latte or a beer somewhere , as for how hot I've seen pipes cherry red down to the mufflers after a good night time run before

 

Thanks for the replies esp oct1949 for the article. NO I am not looking for bragging rights over a latte- I'm leaving in two weeks to ride Rt 10 from Fla to Ca and back and I don't want to burn my boots when moving my feet around on the pegs. Any "can't miss" things on that road that I should look for? Thanks and Merry Christmas..

 

Don't know have the numbers but you sure can light a cigar off those babies.

 

yeah, i don't see it......

 

Don't know the exact temp, but it's hot enough to leave a big a$$ed blister that one time I accidently touched the pipe with my leg.

 

yeah, did we fail science class? you're not boiling water, you're trying to light a piece of paper.......

 

Well, in my science class I found out about heat and its effect on density of gasses and vapors. Also that it is directly proportional.

The short way, hot gas is less dense so it is lighter, if its lighter, if will move easier...
Wrapping a 'tuned' header, one that is designed to scavenge the port, will make it scavenge more efficiently. Not so much on pipe made to blow up dresses or sweep streets or just be 'louder' than stock.

Much more notice-able on a turbo application.


PS: if your buying header wrap, buy it from a car place, its WAY cheaper and there is plenty on a roll!
