Flowmaster
Run Walker Dynomax Super Turbos. They idle pretty loud and when you stomp the skinny pedal they get really loud. A plus is not much drone at all. My dad runs these on his 68 440 Charger 2.5 inches all the way out the back. Manifolds an H pipe right in front of the bucket seats and finished with polished stainless tips. My Dart will soon be running them as well.
