Although they look similar they are in fact very different. Your charge pipe has a higher flow rate, better merge and better build quality. Your charge pipe will support more hp, spool faster and have less wgdc and pressure drop compared to their smaller diameter offering. The chinese will never be able to copy this...Love the update, GC's seem incredible, seriously nice job. Still have some long-term reliability concerns, but big advancements.
Aren't you the first to talk shit when someone copies a design? Your charge pipe looks identical to the one on my car. Identical. Now I'm all for it, competition breeds excellence and cost reduction, and there's really only one way to make that charge pipe.
