New exhaust will be the first thing I have done. My plan is to go right from the dealership to the exhaust shop. I am not sure what way I am going to go. I had Flowmasters on my truck and they were nice. But I want the Challenger to scream. I hear Mustangs and Camaros all the time that have a great deep throaty sound to them. I want that times ten. Dose anyone currently have the Flowmaster super 44s? Anyone have a good recommendation for a good deep loud exhaust?
