Recently purchased a 2017 Challenger SXT more so for better fuel eco vs any of the V8s since I have a long commute. Kind of like a "have your cake and eat it too" kinda thing. Stayed away from the Hemi and scat packs. I'm looking for a more aggressive sound without sounding like a rice burner. I looked into the super 44's, but not sure if just supper 44's will do the trick and if i should do a res delete? Id like the lower type rumble and am aware it wont sound as a V8 but the aggressive sound is what we all desire on our whips. Also, not sure if a res delete would void warranty? Or even an exhaust swap for that matter?
