I am installing headers and 2 1/2 " duals on my 67 coupe with a 302 and can't decide on which mufflers to use. I have the complete system that I purchased from a friend minus the mufflers. I don't want a raspy sound, just a nice throaty grow. I am considering the Jegs Chambered Deep Tone mufflers and a set of Turbo mufflers. Anyone have any imput on which would give me the sound I am looking for?
