Just curious on anyone's suggestions for the first round of modifications for my 2007 GC 4.7. I'm thinking air intake and exhaust for a quick 20-25hp. Any tips from your efforts?
Do the HO cams make any change to the exhaust tone? I know if you go aftermarket cams you can get different exhaust tones and sound by buying different cams, is there any change from stock 05 wk 4.7 to that with HO cams and tune and all the supporting mods?
