tuned. happened after a twenty mile freeway drive. I noticed the popping and sputtering

How old is muffler? It doesn't have a cat, so no worries there but sounds like a plain old worn out muffler. I have '76 with a 390 and have gone through maybe, geez I don't know maybe 8 mufflers and that is exactly what happens
