There is a drone with the packs and the stock H pipe. When you first get the packs on there wont be that much of a drone...but give it 2-3 months and they get louder. I actually love the drone. A lot of times i ride around with the rpms at 2100 just to hear the deep throaty tone.
---Also has anyone with the packs noticed that the exhaust increases in sound volume after the car's warmed up (about 25 min of driving)??? It gets noticably louder after driving for a while. I love it!!!
