2012 dodge challenger SXT V6 deleted 2 fake rear magnaflow mufflers/resonators and found out I already had installed (prior owner did) magnaflow round stainless steel mid resonators thank god! And just deleted rear mufflers and added straight pipes from mid magnaflows. Sounds frocken amazing now!! B4 this sound the fake rear resonators sounded like a Honda. Gkad there off.
