I haver read many posts RE exhaust system and some contradict each other. There are two cat-back "devices" along the tubing route. One is the muffler and the other is the resonator.

1. Which one is the muffler and which is the resonator?

2. Assuming the muffler quiets the engins, what is the purpose of the resonator?

The muffler is first, just behind the cat. The resonator is last, next to the spare tire. The resonator sort of mellows the sound for the ladies. Most of us just cut it off and weld in a connecting and tail pipe.
