Don't wait to hear it! Do it! I have about 40 miles on mine, and how can I say this... . my 04 sounds absolutley awesome. Without question one of the most incredibly loud, but good sounding trucks I have ever heard. I had a buddy of mine drive it today on a dead end street, so I was able to hear it as i stood on the curb, and I told him not to be gentle on the go pedal. All I did was :--) . I wont lie to ya, you will have to be respectful in your neighborhood, and surely don't be a jerk with the black and white around. You will turn heads (more than normal). You will absolutley not sneak in/out of the house w/o getting caught. Lastly, when I say this, I mean it, go to the local truck stop- listen to any of the KW or Petes as they speed up, especially under load- that is what you will sound like.
