only one company that makes headers ??
I was just cleaning my boat. And thought to my self. How there is only one company who makes headers for boats? Does anyone ever make there own? I have a rig welder and could get my hands on all the supplies so I'm just kinda thinking I should tinker around and try to fab a set up

What one man can do so to can another . CMI and Hardin Marine have the SS tubular headers and Diamond Performance sells the cast aluminum Thunder & Lightning headers . If you have the skills and know the proper process , go for it .

Thanks for the boost of confidence. Can some one give me a few pointers or tips for things I should look out for / do as I build them ??

Make sure you use 316l stainless. If you put a magnet on the cmi headers you would think that the magnet would not stick. But it does on the inside . Not good. This means less nickel and will fail. Stainless steel can only fail or rot when it is void of O2 . So these low nickel metals are failing earlier then they should because of carbon build up in the exhaust side and rotting INTO the water side. We have been doing autopsies on the failed headers and it's all the same story. Anyone with headers should use POWER TUNE every outing to release the carbon build up. I have made the change to stainless marine manifolds because of the crappy headers. Also if you cut them open you will see that the water ports are not evenly gapped causing hot spots leading to failure . Good luck in you project I hope it works out

BTW polishing is done either with ellectrolisis or they have a hopper that the header goes in and its filled with water and polishing stones...

There is one company that takes a simpler approach. I forgot their name but they take a header and use stainless sheet metal to make a traingel looking box around the header. This floods and surrounds the entire header.
