The Mazda MPV runs the same 3L block as sable taurus escape. These manifolds, instead of dumping into one bank like the the stockers, they are more tubular and come together. Also they come stock with no catalyist b/c the suvs dont have to pass as high of emissions, but there still is the expansion chamber there so it gives power. Also there isn't that nasty 90 crush type bend in the front manifold. Flows better with a lil better tone.
