Hi, I have a 67 Dart with a 416 stroker with about 10:1 compression, not sure of cam size. It has long tube headers and 2.5” exhaust with flowmaster 40s. I’m looking for quieter mufflers! The flowmasters are loud at idle, but surprisingly, the droan isn’t bad on the highway (3.23 gears). Would Walker quiet flow work? Thanks, Brian
