My Borla was very well made, relatively light weight, bolted up perfectly and sounded great. I just could not live with the drone. I was running it with the secondary cats in place. I replaced it with a FVD Brombacher Sound Version and am very happy now.
I did toy with the idea of adding a balance pipe between the outlets of the Borla mufflers to try and tame the drone but never got around to it.
