I had one on for a week. The drone between 2-3k RPM's was simply too much for me. I had the stock put back on and returned it. (They did offer to send another but I was already out 1k in labor at that point.) The frustrating part was it's advertised as no drone.
I suspect winter hibernation. I'm just a bit north of you (Indy) and there is still a bit of road salt residue and pot holes/craters. I wait for a good amount of rain before I get my toys out. And yes, I'm jealous of your weather/road condition! Good on ya.
I put the Borla S-type on. The drone between 2200-2900 rpms was deafening. I had it switched back to stock after 1 week. It had a great sound but running around town was unbearable with the drone.
