Recycled exhaust manifold
I attacked my 1.8 manifold with a 4.5 inch grinder and a stick welder.
4 hours later and voila! my no hit block special is born
next step vband!

Any pics of it mounted to the head? Thats some good welding with an arc welder in such a small space. Bet it was a pain on the insides of the runners, or did you weld them up, and then weld it to the flange?

viperormiata, Full_Tilt_Boogie, pdexta, Miater, 18psi, Thank you men. Praise like that makes me feel alive!
The welding was easy enough. I welded the collector up first, then the runners and lastly the slip joints at the flange and collector. I used a small rod (1.6mm2 308 stainless) which is good for getting into tight spots.
(For a crazy but simple solution how about tying a stubby downpipe elbow back into the stock 2 to 1 piping flange and a close on vacuum operated screamer pipe through the hood! As if there isn't enough drama all ready when boost hits...but having to contend with a rocket launch as well!)
It may be a while before it gets mounted as the current set up on my car works well. Possibly a winter project.

How about using a heat riser valve dumping to a screamer pipe? Has any one tried this? It closes with vacuum / opens with boost.
Probably a cabin mounted manual boost controller could be used to ramp the closing time or lock it closed.

Honestly that ^ seems like a better option than the spring flapper in the muffler.
I also have the feeling this manifold will have a deep subbie type growl.
When the 2nd cylinder fires, it takes a longer path than the next #1 cylinder then they meet about together. Then the 3rd cylinder fires takes a longer path than the 4th and again they meet together.
