Are highflow catbacks worth the money for a 2009 300C 5.7

[jimmyc8000]

I am kind of new to this game but I recently installed the 93CAI tune to my new ride with an AFE cold air intake system and it runs great. I was thinking about getting some high flow catbacks but I wanted to ask some opinions from the forum members before I jump into it. My days of loud exhaust are long gone and I was looking for something with a similar sound to the stock exhaust system and my question is is there much to gain from an exhaust without touching the motor. I know some of you have a lot of experience with this so I figured I would ask, thanks again

Well, at twice the cost of a Predator a catback will generally add about 5-8rwhp on a good day, so it is mostly for sound/looks...
