So i just got back from Parris Island and have a little cash to play with i am curious on some things. First off i hav a 2006 300C 5.7 Hemi with a custom built CAI and removed the suitcase muffler. So here are my questions: What are the power gains with the long-tube headers and with the long-tubes do you have to remove the cats? Also has anyone done the JBA shortys, how are they in comparision to the long-tubes?, Where can i get the tinted circular headlight covers and tinted tails? With the Eibach 1.6 kit how is the rear suspension done i can see the front springs and how they are but i am lost on the rear does it change the whole setup? How do you get the stock grill out i have tried and tried to figure it out and still i am unsuccseful. i am also wanting to remove the speed limiter and get harder shifts i know jet has a chip does the stage 2 accomplish these things? Thanks in advance for all the help i know will be heading this way.
