Unless Wagner plans on selling this thing to the general public, I highly doubt they'll be putting in the necessary R&D for the optimal design. Seems to me this effort is an effort to get something "better" than the stock plastic one for forced induction.
Wagner is however planning on marketing and building a T/C kit for the V6 Mazda 6. So I'm not sure if this will be an option with that kit or if this is just a way to make a few bucks off of some customers who need some custom fabrication done.
