64 Dart needs new muffage

Oh, hell, I'm WAY past that THANK GOD.
It was my points mainly, and timing, but all fixed now.
Got a lousy tune-up from a young mechanic who, you know, just doesn't know these old Mopars (I'm learning myself-All the time!)
Yeah, I totally had to make sure I wasn't gonna 'pop' a brand new muffler before I went a bought one!! (Good thing too, cause there were a couple other, smaller, backfires I had while getting the car tuned. So now I'm ready to fix the muffler. It's a bit*h trying to hear how your engine really sounds with a big ol' hole in the front of your muffler!! Now that it's tuned, I'll bet it'll sound really good, not racing good, but street good.
