Recomend an exhaust

I have a '73 Dart Sport with a 408 stroker. I went with the TTi step headers and 2 1/2" exhaust into Flowmaster 10 series mufflers. I hated it. The rapping noise and it was way loud. I went to true 3" rolled pipe into Flowmaster 40 series and added an H pipe. No more rapping, and I can talk to someone when driving. When I get on it, it draws attention. I love my set up now.
