I have been hotrodding since the early 70s so I prefer the old school sound. But I find as I get older I like a bit less noise so I can talk while I want to get peoples attention with the loud pedal. I prefer the sound of the Flowmasters over the Magnaflows, they just sound right. I'm currently running 3" exhaust front to rear and started with 40 series but later changed to 50 series mufflers. I have considered adding an H or X pipe, but I don't like how they change the sound. This is an older pic when I still was running my old ST10 four speed but the exhaust is essentially the same except for 50 series mufflers and longer turn downs now.
