Man, this is my favorite topic.

First off, Creative Design Concepts (that did the Shaker for the '03 Mach 1) says their current Charger set up will work with the Challenger - I spoke directly to them.

Secondly, I as others, hope they'll makes the "concept" hood an option or via Mopar Performance. That hood had the ducting that Deranged mentions and with the K&N filter over the radiator support. That would be the best, even though we lost the "Butterfly" valves on the scoops that was my favorite part of the car. Reminded me of the '70 road runner/GTX hydraulic Air Grabber scoop that raised when you hit the button...Awesome still today, 38 years later!!
