Default DIY SS Bottom Mount Manifold

I got all my goodies from Weir Tech yesterday and today decided to play with them in the garage. They are Sch10 SS Weld elbows. I'm going to be running a 3" allumanized steel downpipe since i've got tons of bends leftover from my exhaust build. One thing led to another and I actually ended up cutting the collector and tacked it together.

I dont have a chop or band saw so I had no way of making a super accurate cut. I ended up putting it level in a vice like so:

Then eye-balling the cut and going to town with my hack saw:

I wont lie, I had to do some grinding to get them to fit correctly, but i'm pretty pleased with how it came out.

Next I took the collector and lined it up at the rough angle I wanted it to be on the runners.

Then I taped them.

The rest are just various pictures of positioning i'm playing around with. I really wont be able to determine my final alignment til I get this on my spare engine and borrow a turbo from someone to check turbo-block clearance. I'm also a bit concerned about fitment in the engine bay near the steering column (if thats what its called).

More pics just cause I wanted to have more than UrbanSoot ever has in his build threads.

You did damn well for using a hack saw. I can't even cut a hockey stick straight with one of those things.

I think it was something like 125 bucks shipped.

Like I said, it took a fair amount of grinding to get them to fit the way I wanted

I cant take credit for the exhaust, Bob Bundy made that and I could never come close to doing as well as he did...

Its awesome. A friend of mine that is a pro welder was extremely impressed with it as well.


Speaking of welding, I'm beginning to think that i'm going to have to pay someone to tig this manifold when i'm ready...I really cant afford to buy a second bottle for the tri-mix of gas.

What are you using for gas right now? argon works fine for stainless, you just need to back purge it.

But does argon actually work for mig welding? I thought it had to be trimix or it was bust.

If I can do argon with stainless wire, i'll be happy.

Im sorry Im thinking tig, didn't realize you were using mig. Im doing some tig for a structural steel shop tomorrow and they mig stainless all the time, Ill ask them what they use and let you know tomorrow. Ive done stainless to mild steel before with standard mig wire and a 75/25 argon co2 mix but I know thats not what you are going for.
