Big Block muffler choice
If you want it quiet and efficient. Straight-thru ovals. If you have room, run 2 on each side. My e-body ragtop is dead quiet, till it's eating. It doesn't hurt performance. I run magnafow stuff. It's well made and thought-out. If room is an issue, 3" bullets will work as resonators. I've done this stuff on many cars. I like quiet.
