Has anyone used these before?
TurboFab
Any feed back would be great.
Thank you.

Looks like a solid manifold, I also like the fact that it has a good W.T (wall thickness) compared to the lame sus304 shit. I'm not a fan of tube manifolds as they tend to crack... I'm a professional piping designer, so don't even start with me. If I were to go top mount, i'd get something made out of cast iron; but that's just me...

make sure that wastegate placement isnt going to bite you in the ass later.

a tubular manifold will only crack if its poorly made.

i have that manifold (that pic is actually of my manifold i was told by them - and they told me they actually only made 3) they're no longer in business and have moved on to something other than making manifolds or radiators.

if that place has one in stock - and you get it - it will limit turbo selection to ones with vband outlets and 4 bolt gt turbos. I had to customify everything and it took many hours of fabricating to get things right.

its stainless 321 and its BEEFY - wastegate placement is fine. but the turbine is like RIGHT AGAINST THE HEAD - AND THE DOWNPIPE MUST TURN IMMEDIATLY TOWARD THE DRIVERS SIDE EXITING THE TURBINE

If you don't plan on fabricating everything yourself - this is a wicked manifold and a great choice, but i doubt you'll get one from anyone (unless that place has it sitting there - not likely)

Thanks for everyone's input.
I'm a welding inspector so the 321 and wall thickness really appealed to me.
If anyone else has any input, please don't hesitate to add a comment.
