Megan headers vs OBX headers...

That has always worked for me and all the customers I've had.

Yeah i stuck that stuff on my last gasket, it didnt hold worth crap... are you supposed to bead it, or put a thin layer?

[d112crzy]

I bead put about a 3mm layer on there.

Mate it to the surface and don't torque it down all the way. I wait a few hours, then torque it down. Wait at least 12 hours before you start the engine.

A pain in the ass because you have to wait, but it's worked flawlessly for me.

we had the permatex rep, come and talk to us about their product, everyone uses their product, hondabond is permatex, you have to follow some rigorous steps for it to be effective, but it should work right if done right

Thats probably why, i put a film on the gasket, torqued it and went, cause thats what i was told to do, if i have to let it sit, its gonna have to wait till the weekend... But being a rubber gasket, doesnt this stuff just burn away cause the header gets so hot, or does the copper somehow take the heat instead of the rubber.. i dont understnad this stuff and the permatex black RTV, i know the black is oil resistant made for oil pans, seals, and valve covers.. but the copper stuff is just... wierd.

I don't know how it works, I just know it does.

Mine was still present after I took the header off once.

wow, thats a great tip. Gaskets were the only thing I was worried about. I asked a few people abou the flex pipe lengths... nobody has gotten back to me. Though I think the megan pipe is longest. Looks like Megan is the way to go.

Great tips though! thanks all!

i dunno its a bolt in piece it should be the same size as whatever part is coming out of it.

well i know this thread is about megan vs obx, but I've had my DC sports header for years and not once have i had to replace the gasket, i've probably taken it off twice or three times and it still seals. Maybe its b/c its a round crush gasket that seals each individual hole? idk, but all i know is i bought my DC header brand new for 225 shipped and it's worked flawlessly.
