GX 550 OT+ exhaust buzz low RPM

[IARob]

I had the exact same issue. The fix for my OT+ was wrenching down the skid plate, it was vibrating. Really needs a rubber spacing washer or two.

Did you take yours to Bergstrom to fix? I was in there a few weeks ago and even though I told them how to replicate, and they could hear when I drove, they couldn't replicate. I will have to reference you skid plate next time I am in there. My sound seems to be coming from in front of dash so that would make sense more than exhaust referenced by others.
