ya but you can buy 10 of those for the price of one well built one… Im not saying that thats the way to go but its not a huge tragedy to do some spot welds for something that can be replaced easily in the future.
i got one of those and i have had it for 3 or 4 years with no problems so far.
However, the manifold you made is georgeus and i one day would like to own one lol
