OK, just got it installed.
Flowmaster Force II kit- has 3 inch pipe, resonator, 70 series muffler, and polished stainless tip. Bolt application.
More quiet than I expected, but louder than stock. Gives a good throaty sound on acceleration. Nice and quiet in the cab at highway speeds, but you can hear it during passing. Overall I am pleased, but was hoping for a little deeper sound. Performance is slightly improved, I can feel a little better response from the pedal. I am hoping for better fuel mileage.
