I bought these for a project three years ago thinking they would be great for a twin turbo setup.
I have now gone a different direction and no longer need them...
I've heard them referred to as Lightning Power Products exhaust (before it became Keith Eickert Power Products)
or as "Drake" manifolds as well...
The ports are 2.1" each and run all the way to the riser.
They are in excellent shape. NO leaks..
