No drone, it sounds really good actually. I pieced together my current setup from a Gibson cat back system I had. So mid pipe is the Gibson 3" going into the Thrush, and then 3" tubing on out to behind the passenger tire (still tucked under the truck). I finished it off with a 3.5" echo tip. The drone usually comes from not running your exhaust out the back or side. Dumped looks good, but can be very loud.
