Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

My '67 with a 350 had Flowmaster 40's and I had the same problem, too loud and too much drone in the interior. I had them replaced with 50 series Delta. Perfect! Nice exterior sound, no drone inside. My wife and I can now carry on a conversation at highway speeds without shouting.
