I have a automatic r/t anniversary edition and get 22 mpg combined, the car is completely stock, I would like a little more rumble without a drop in performance and mpg.I read threads about resonator delete and thoughts about if it is the way to go. Thanks Tony

Replace the mid mufflers with straight pipes. Cost between $100 and $150.
You with get that extra rumble and none of that annoying drone you will get
if you remove the rear resonators. I know from experience.

Thank you for the welcome. If I change the mid mufflers that will take care of the sound,but what will happen to performance and mpg? Thanks

Very little change, if anything both mileage and performance increased slightly.
You could always add mufflers back or do a complete cat back system if your not happy. Pretty much everyone here who has done this was happy.
