I have flowmaster 40's on my 383 with cheapo flowtech headers. Sounds good at the stop lights but has a drone at highway cruise, But I have a set of thrush welded and a new set of doug thorley tri y's sittn in the garage ready to install.
I would say go to you tube and listen to some sound clips (they have any kind of muffler you could think of) and find what you like (thats what I did) I like the rumble the thrush has but seems to quiet down with acceleration 9at least from the sound clip) I guess we will see
