Hey guys...so I have an exhaust on my Miata that causes A LOT of drone and vibration/resonance through the cabin. So I was wondering, if I was to get a 23" cherry bomb glasspack or a long vibrant resonator installed in the midpipe, would my interior stop vibrating and would the drone be cut down? It has a resonator in there right now, but I'm thinking of adding an additional one. When I mean interior vibration and resonance, you can literally feel it in your head.

I had a '94 Miata with an exhaust that sometimes sounded like metal ball-bearings being shaken in a glass jar - awful!
It turned out that the driver-side motor mount had failed and was allowing the aftermarket header collector to hit the frame at times. The fix for me was a set of stiffer (mazdaspeed?) motor mounts.
Maybe good to check for (marks on the header, frame) on your car too, especially if you have aftermarket exhaust.
