Hey guys, new here, just purchased my first Mopar. Recently pulled the trigger on a 2016 charger RT 5.7L. I’ve grown up on Ford and owned a mustang GT converted completely to Shelby/custom. I will never go back now! I do have questions though, I’m thinking about doing mid muffler FM 40s and reso delete, but am also looking at long tube headers, need opinions experiences with kooks, bbk, and any others - what type of performance gains, sound, and is there anything I need to be aware of? Any input would be appreciated!
