    Flowmaster A/T Moderate or Aggressive?

    Crescent Wrench you were right on. I had the AT Classics installed. They sound great but drone if I am between 60-65. I love the sound so much I am willing to stick with it.

    Newbie Upgrade Question

    I have an appointment next week with the Dyno/Tune man and that's my chance to add the next mod. If sound, and "feel," are valued more than hp gain, what would you recommend for my next upgrade? I have a 2006, GT, automatic, convertible which is my day ride. I do not want to increase gas...
