Im new to car performance so I hope this question isn't too stupid. I recently purchased a 2011 Challenger RT. I know I want a ProCharger later. I want to upgrade my exhaust now. I want my care to sound like it looks. I have listened to a lot of clips. I like the Corsa and Borla exhaust systems. What will new headers do for my car? What kind to get? Are they really necessary? Do certain ones work better with Corsa or Borla? Do they make any for the 2011? Thanks again for any help.
