Jay:
I had a similar problem involving loose baffles which would migrate to the
front of the muffler every time there was a semi-hard stop. Shortly after
there would be loss of power, inadequate running, etc. until roughness in the
road would restore normal operation. This defeated some good mechanics for a
while! (Moral: Do not buy cheap baffled mufflers!)
