    hi everyone, my friend was driving my 83 chevy k10 on the highway the other day, and he kinda pushed the baby hard...it hit 80 mph
    (a new record lol), but when driving home, i noticed that it was louder than usual...having an exhaust leak before this (but now fixed) between the headers and the pipes, i figured it happened again, but instead, the muffler had a huge hold in the bottom of it (1 out of 2 mufflers). my question is, this was never there before, in fact, the mufflers seemed in pretty decent shape to me...could he have blown out the muffler? is this even possible? or was it just rust that finally came loose? thanks.

    Yes it could have blown it out from the heavy acceleration if it was at all rusting. Particularly if there were a backfire out the exhaust from running rich or timing being off a bit. Sounds like it rusted and was about to go anyway from the fact that it needed the other repair.
