Imagine talking with another person face to face. Now imagine that other person in another room, in a closet, with the door mostly closed. Carrying on a conversation would be harder because you wouldn't be able to hear 'em.
The exhaust pulses from an engine start out really loud but the shock waves go through one third of the muffler, through a small opening into another room, to the other end of that room, then through another opening into a third room, to the other end of that room, then out the tail pipe. That's like sitting in a closet in your house and trying to talk with someone standing outside, ... In the garage, ... With the doors closed.
