Hello everyone, brand new here and looking to get some feedback from you who have upgrades on your challangers. I have a 2018 SXT. I'm looking to get the following upgrades; cat back exhaust (magnaflow sounded nice) hp tuner, cold air intake, large diameter throttle bottle, high flow catalitic converter. If anyone has good brands they bought and like I would love to know about them so I can research them. Or if you have any other upgrades you've made I would like to hear about those thanks!
