Yet another exhaust manifold
Here is my fc manifold.
Flame cut all flanges from 5/8 steel.
5/8 may be overkill but I would rather
not have to worry about it.
The cross brace is just to dampen any
vibrations, again probably overkill..
tubing is 1&1/4 i.d. (weld els). I used
2 - 90's 2-45's and 2-2"to1&1/4 reducers.
The front tial is real tight but it fits.
I just got it back on the road and have
not really loaded it down yet.
What do you guys think??

Looks pretty good to me. I would have used larger diameter piping though. Those flanges sure as hell won't be flexing and cracking!
Are you routing the WG's back into the downpipe?

Right now the gates just have 3" long dump tubes,
I will probably just leave at that, unless it gets
real annoying. 1&1/4 is probably the smallest
reasonable size. My main reason for keeping it
small was to minimize the volume of the tubing
before the turbo without restricting maximum flow
too much, which should help keep spool time down.

looks a lot like mine!
Except I went with the 1.5" sch 10 pipe instead of the 1.25". I like how you have that transition from the port to the smaller runners. I'm not sure how well it will work but looks neat

is it mild steel piping?

Yea they are tial 35s. The welds els are schedule 40,
Which has a pretty thick wall. Any industrial plumbing
store should have the bends. I think I spent $90 dollars
on materials, the gates were another $215 each (from
roadraceengineering.com). This thing is heavy! but it
should last a long time.
The dual open gates sound pretty cool, not as loud as
I thought they would be.
The car is pretty damn fast compared to the stock
turbo.
here are the car specs:
1990 t2
street port
haltech e6k
550/550
to4e .70 ? exhaust side
.45 bar max boost
2.5 single ss exhaust
