    Default Header coatings.

    I really like the idea of dry headers, no water mess in the boat from leaky header lines/weep holes, no dirty water on the transom of the boat, etc... My biggest concern though is the heat, i have kids. How well does the coatings keep the pipes cool, i know that ceramic coatings can help direct the heat out of the pipes, but how well does it work?

    i run dry coated header and love them, they cool down very fast. i ran them all last summer and it was the first summer i didnt get burned. my girlfriend fell on one about 2 minutes after we shut down and didnt get burned, she said they felt hot but no burn, if they were not coated she would of had blisters.

    same here, my kids and wife hated the dry shorties i ran on the tx19, i switched up to coated dry up swepts and all were happy. they'd cool to the touch within 3-5minutes depending how long i was into the go peddle.

    Dare to be different, if it turns out great you can claim you planned it that way.

    No doubt a dry coated vs dry non coated are alot cooler, i'm trying to compare dry to wet though. I find with my wets i can pretty much tap the headers after shutdown and they wont burn me... that is as long as i wasnt doing alot of idling before shutdown. I'm not running a ton of water, i have restrictors in place..

    they will cool down faster with the coatings.. usuallyu touchable in 5 minutes or less.

    but they will still burn you and very badly when hot with or without water... Also the coating will not hold up to dry use. it turns foggy and and starts to look ugly.

    if they turn foggy, just need to hit em with the powerball and alum polish, brings the shine right back. i ran about 200lbs of nitrous threw mine(400hp 2 stage on a 505 13.5 to 1) this past summer, and they only turned near the heads, bout 4-5inches from the head. i kept them cleaned and they stayed looking new for the most part.

    It will hold up to being dry. I run mine dry and they only frost the first 6-8 inches from the head.

    Now if you retard your timming to much, they will look like shit( ask me how i know)

    Just run a manual valve so you can turn the water on and off. That way if you see a cop you can turn it on and if you racing you can turn it off.

    If you do coat the headers talk to Jeff at Embee
