Hey Honda tech I have a fully ported oem manifold with upper, mid plate(Tig welded), and lower plenum ported and polished. I spent $200 just in Tig welding the underside of the lower plenum, welded mid plate, and upper plenum welded the iacv and throttle body air bypass so you can port the throttle body as large as you can. Includes billet egr block off plate and gaskets for the upper to mid plenum. Hours and hours went into porting this manifold to perfection and will make way more power than rbc, rrc, euro r, and the skunk2. Most shops charge $600 just for the lower plenum and that's not including core exchange. Please don't low ball me on the price this manifold is one of its kind. Asking $600 firm. The midplate is Tig welded inside and out and ported and polished flush. Plenum volume was ported for maximum displacement and upper plenum the iacv was welded and ported flush. Please pm me if interested I'm firm on $600 located in orange county.
