I would love to do a 2/4 drop (coils and an axle flip) and I am pondering a rear gear change.

What type of intake and exhaust changes are you talking about? I'm not a big fan of the K/N deal and would rather have a WAI of some kind. Right now it has some sort of exhaust on it I haven't seen before. It looks like a rectangular "pillow" shape with a tomato juice size can before it. Very different than my old truck that had a standard CAT and oval muffler. The tail pipe is the same twisted mess on both trucks. Four 90° bends if I remember right. I wonder if an exhaust like the ones the Lightning Ranger's had (45° from behind the muffler headed out the side) or just a custom mandrel bent pipe nicely flowing over the rear axle and straight out the back would help.
