Truck manifolds *Pic*
I've been scratching my head for a bit trying to figure out which way I want to go with Turbo headers. I trip over these stock manifolds every day in the garage and finally got to looking at them (as I was about to throw them away.)
After googling them for a bit it appears these may be the ones that are being used as the manifolds for the Turbo swaps. Can anyone confirm?

The passenger side seems to be just want I want. The drivers side on the other hand will never work with this crazy height. I can't flip it to run out the back because I'll have to run the crossover all the way around the car.

Is it normal for people to use 2 Passenger side Manifolds? I know it doesn't really matter and everyone's situation is different. I think it will make the Drivers side a better fitment for when I fab up the hot side. Here's a picture of the Passenger side flipped facing down on the drivers side.
Deff looks longer.
Mine are
GM 12571680 (driver)
GM 12578342 (pass)
Also have a set of
GM 12616287 (driver)
GM 12616288 (pass)
both appear identical.
There are many variants of manifold (some stamped steel even) that came on the trucks. You just have one from a different truck than the standard 01-up cast 5.3/4.8 junk. It looks like it will flow great though!
Just log those off, weld v-bands on and go to work. https://ls1tech.com/forums/eastern-c...ds-vbands.html
