    2nd/3rd Gen Exhaust Manifold Comparison

    There is no 2G swap carb legal intake.

    California smog is stupid.

    You will find some places don't care, and others pop your hood and fail you.

    As for the reason for dodge switching manifolds was "room" for the emissions crap.

    The 3rd Gen manifold is trash, and the second-gen has equal flow, whereas the 3rd gen forces cylinders 5/6 to push air harder with my backpressure reason why 2G swap sees huge numbers gain in lowering EGTs.

    I want to swap to a 2G because I need to rebuild my shocks and get my axle moved forward.

    I am slowly getting there.

    2nd/3rd Gen Exhaust Manifold Comparison

    From my swap, I noticed a considerable drop in EGTs.

    I liked the EB, but electronics always fail, so I swapped her.

    The kit i bought had the 3-piece BD manifold.

    The big difference from the VGT manifold to a 2G is the location of the flange.

    What the 2G does is it centers the flange in the middle, thus giving you better flow rates and the biggest.

    I would say 300 to 400 like stated above on the EGT drop.

    You will love the swap without a doubt.

    Down the road, if you do or will pull, you can buy an inline brake, which is the same as the VGT setup.
