I know the z5's are a small gutless wonder and many people believe it is pointless to try and get much from it. With that said, has anyone tried to make an exhaust manifold for the z5? Have it be just a better stock replacement, or one that also replaces the pre-cat?
Just curious if anyone has and what was the results. Figure it probably would't be much gain, but nickel and diming hp could eventually be beneficially I would think.
