can you weld a turbo manifold with a mig/ wire feed welder?
as the question asks, can you? i have heard people talk about it but i was wondering if anyone has ever completed a turbo manifold with a MIG welder? i have search and couldnt find anything on the subject? any help would be appreciated or any links would help too.

yeah wire feed mig. no problem. i welded up a log manifold with my buddies 110 miller welder. ( with gas) and its held up since 2002. finally cracked and i just rewelded it with my tig. went over it.
KEY !! is prepwork !! bevel the ends to get maximum penetration.
check out bailhatch he mig welds his manifolds.

I just built a ram-horn with my 175a Lincoln mig.
the welds are FAR from pretty but they're functional
expect pics in the next day or two

I did mine. Welded with non stainless wire and used 75/25 mix. Should use stainless wire and helium tri-mix gas. Cost about $200 with tank. I'm coating mine anyway. Not nice looking weld but harder to do when using the wrong gas and wire combo. They are strong tho and the welder helped, that sp175plus is amazing. here are 3 steps they go with the 3 pics...
1. Started with this
2. Used this
3. 10 hrs later got this....

Beveling the ends is defintely a good idea. You want extremely good penetration. If you dont get good penetration all around, after a few heat cycles it will crack.
If your welder is powerful enough, you can just go at it.

i'd post mine that i just made but the welds look like **** and the collector obviously isn't symetrical on any axis 
it works though; i guess i'll find out in the next few days if i made sound enough welds

Sorta back from the dead.. Is the only reason they will crack weight from the turbo? I plan on bracing mine, so should mig welding not be a problem? I'm pretty confident in my mig welds, but I hate re-work. I'd rather try to find someone to TIG it for me if there is a pretty good chance the heat alone could crack it.

no they can crack because the weld doesnt get enough penetration and is too thin, then when it gets heated up from running the car and cooled down over and over it expands/contracts and causes it to crack
