It’s a Borla system, which is always good, had one on my 911. However, for the Box I’m concerned about drone. Anyone have any experience? Thanks!

I just removed a Borla system from my 2004 3.2 6 spd (installed by the PO). For my ears, very heavy drone from ~2,500 to 3,000 rpm as installed on my car.

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.
