Hey, sorry, this is actually a question about my 1965 Mustang Fastback: 306, Edelbrock RPM package, etc. (I do have a bullitt though) Well, we have a pretty radical lope, hooker long-tubes, off-road H-pipe, and 2 2-chamber flowmasters. What would be the better alternative for a muffler with excellent tone, but not drone so much?
