I had to delete the sound clip I had of mine (needed the web space), but I do have pics if you click the link in my sig. The sound clips on the Hooker site is with their LT headers and x-pipe in addition to the AeroChamber mufflers. To me, the sound is a lot like the Flowmaster kit. There is a LOT of deep deep bass at idle. And at 75-80MPH (I have 4.10's so my RPM's are different at those speeds than a car with 3.55's) there is NO drone what so ever, in fact they are quieter on the insterstate than the stock mufflers.
