My Corvette had a big plastic tub sitting right over the Mufflers. After installing headers and HFC's I had an issue. It resonated like a Bass drum. On Vette's the drone RPM is 16-1800 RPM's which is easy to work around with the next lowest gear selection. Regardless, a liberal coat of Second Skin Damplifier helped quite a bit. Maybe 25-30 lbs worth. Some Z guys have done this...Check over in the Audio section.
