If you already have a stage 1 set, you only need the upper manifold.

Stage 2 manifold requires a riser, it will not fit on the car without a riser

Our Stage 2 BK1 3.8 manifolds offer the same mid-range torque as the stage 1, but improves the top end by eliminating the oddly shaped and narrow mouths of the runners. We cut the manifold in half so we have direct access to the ports to get them to the perfect shape, letting your 3.8 breath until redline!
