I have a 2013 limited 3.5 with the factory 20 inch chrome and cream leather. I have added new tint,chrome door handles,AVS visors,a spectre ghost short ram air intake. I recently deleted the resonator,added a 93 octane tune and Thursday I am taking the rear muffler off and trying a custom made exhaust that myself and my shop guy came up with like a twist on a straight pipe but not as loud. Guys I need ideas as in should I go headers next or dyno tune. I can't find a throttle body spacer of course and I want to upgrade the suspension. Help!! Lol
