I am just finishing up my 67 Coronet RT convertible. It runs but not well yet. It is a stroked 493 cu in with 1100 Holley, Eddie heads and intake with TTI headers. I have tried a few mufflers but it is still too loud and there doesn't seem to be room for resonators. Any suggestions?

You didn't mention what size pipe you have but the bigger it is the harder it will be to make quiet. Header make it even harder to quiet it down. Did you try walker quiet flow? The 2.5" in/out part # is 21548 summit sells them.
