Would anyone be interested in a group buy from Kinetix in the states? I'm in QLD. I want to order some cats and a plenum

Hi guys first post! I just bought a v35 and I'd like to put on an exhaust. I've looked at these two systems from Australian suppliers which seem very reasonably priced but I can only find audio of the ultrex one. It sounded great however. Has anyone got any experience with either or a recommendation? What would an exhaust shop charge on average to install it? Thanks for your time, I can't wait!
