No, he plans on manufacturing them for sale. The exhaust manifolds are designed, 3d printed, test fitted and now ready for production. Ash is not as quick getting these to market as he previously thought but I fully expect to see them on the market in a few months. All of the hard parts are done. Apparently he is now focusing on the intake manifold production. I believe he plans on dyno testing a prototype intake to prove its gains/benefits before going further though.
