you said your exhaust still sounds louder. any chance the muffler shop ripped you off and put a used or bogus (or non at all) catalyst in your cat location on the side they replaced? that might cause the type of left/right bank imbalance that could introduce vibration and would also account for a different exhaust note and the CEL.

just some thoughts. sorry your having trouble.

I've checked the motor mounts a couple of times over the past year. They are in good shape.

I purchased the cat myself and have removed it once to check the honeycomb elements. It's all there. I also peeked at the cat element through the y-pipe a few days ago while changing the graphite donut gasket where the y-pipe connects to the muffler.

Appreciate the help.
