Reduce drone noise

[NormD]

I have a 302 with about 325hp using flowmaster delta 50's. I want to reduce the drone and quiet it down some. I am told using flowmaster resonators will do the trick. Anyone have any experience with resonators? tks, NormD

You know what will probably get rid of the Flow drone? Installing just one resonator on one side of the car. A very short glasspack would probably have a similar effect. Ford more or less did the same thing on the Fox3 GTs; one muffler was bigger than the other. I put an American Thunder(Flowmaster) cat-back on my '89 GT and I honestly think it damaged my hearing from the drone.

another thing you can try is offsetting the mufflers some by about 3 inches. otherwise i'd say add a small glasspack inline in front of each muffler about halfway between the headers/manifolds and the mufflers
