Good sounding muffler
I really enjoy the way the flow master super 40 sounds. Was exactly what I was looking for. Not to loud but still has a classic sound to it.

Great sound
Not overly loud but offers a nice deep tone. Clamp on is probably quicker. Mostly welded mine on since the bed was already off.

Perfect
Stock catalytic converters, stock resonators, only swapped mufflers and it’s perfect. Not too loud, not quiet, opens up the exhaust.
