I know that a lot have the Borla Stingers, but I'm curious if anyone has purchased the 11752 kit and how do they sound? I have a 2006 Convertible, so I'm concerned about the droning from the stingers. I had a Borla exhaust on my Mazda3, I loved it at first, but over time, the system proved to be just a tad bit too loud. I'd like a bit of a rumble at idle.

I have the borlas and to me to have something nice at idle you have to get rid of your cats otherwise it wont make a difference.

 

The Borla S (11750) idle on a warm car, with cats, is far from a rumble so the 11752 aren't gonna do it for you either. You'll get some drone with the "S" but top down or windows down isn't all that bad. I find windows up mildly annoying, now and then, but well worth it for the overall sound.
