im looking in to building my own custom header and my question is would 16 gauge (.065in) think mild steel piping capable of taking the heat that a 13b n/a would produce in racing conditions?? and if so how long?? im most likely going to make it out of 304 stainless but i would like to know different options.. since mild steel is alot cheaper but as they say u get what u pay for soo....i dont know

thanks for your time

My FB had a not very stainless looking header on it's 12A. It was really rusty and beat up but it worked fine. It never did me wrong. If that thing started out as stailess then you couldn't tell by looking at it. It was pretty heavy walled though and I never measured it so I couldn't tell you how thick to make yours. But hell mild steel is so cheap you could make one for almost nothing an toss it if its defective.

Just make a thick flange for the engine side because mine was really thick and the piping was nowhere near as thick.

 

rene from rms will make a header for you .

 

.065 has worked for me in mild steel. Just make sure you use back-purge with argon while welding...

 

ive actually talk to him in the past and will most likely have him make my entire system once i get everyhing i need but figured i can attempt to make the first one to get my design down first

thanks for the tip
