Hi All.  Been a while since I checked in.  Did anyone ever get any relief from the booming/pressure/buffeting by installing the Borla exhaust?  Back in the day, probably 2 years ago now when this thread was on fire, adding/replacing exhaust was being experimented with before focusing on the tires.  Just curious... 

 

I didn't get the Borla, but my 'booming' over bumps was eliminated by clamping weights/dampers on the exhaust.  I included pictures further back in this thread if anyone is interested in quantity and placement.

 

The buffeting was a result of tires.  It took 6 Continental replacements to get them quiet [under 10lbs] and I had them re-road force balanced when I putting them back on for the summer.  The Continentals have a tendency to flat spot which temporarily re-introduces buffeting.  I'm going to put up with them a little while longer and replace them with some Michelins for summer duty.  My BFG KO2s are awesome and don't introduce any buffeting.  That's probably why I left them on until August!  If it wasn't for the fuel economy penalty [they are 14lbs heavier per tire!], I'd leave them on year round.

 

The vibrating was fixed by replace the rear end.

 

I've been enjoying my Yukon ever since and only experienced a failed wheel bearing since.  While the root cause of the issue may never be fixed or identified on these models, I'm OK knowing that I can control the inputs [shitty or out of balance tires].

My biggest improvement came from 20" wheels on KO2s religiously RFB down to 15lbs or less ... but, I did install the Borla touring and noticed slighter improvement still
