this is what I did to my R/T when I first got it. I cut the the bottle mufflers and resonators off. Then I put flowmaster super 44's where the resonators where and ran strait pipe from where the bottle mufflers were. It sounds great! I love it. The other day, when I took my car to the dealership to get an oil change, everybody heard it for the first time and they couldnt believe how it sounded. Everybody was staring at me as I was pulling into the dealership. The guy who sold the car to me a year ago asked me what kind of exhaust I had on it and he said he loved the sound!
