I put on flowmaster catback system and a K&N filter. Not sure if it really helped alot but it sounds tough as anything out there. It wont spin the 20" tires but it does seem like they are thinking about it. all in all i spent $300 for both.

K&N filter, flowmaster 70 dual, AIM intake tube, tonneau cover no big improvements. Especially in the MPG game. Truckin did a piece on the JET piggy back module. The dyno run says 25hp gain. Not sure if the computer is counter acting the mods so far. Right now I would say that nothing is really doing anything other than making my checkbook lighter.

For the 04 Hemi, my pick would be the Dynatech precat system. They really make some power. If we had a good programmer for the 04 though, that would be my choice.
