Safe to say that neither of ours are now properly torqued.
I always keep a sack handy. One of these days I'll replace them and properly torque them.

I also had him replace my guibo and center support bearing (I never got the old one back, so I assume it was replaced), so they would have had to remove the rear reinforcement and drop the exhaust.

I've had a ferocious vibration at cold idle ever since I got the car back.
Feels like the exhaust, but I've checked, and it doesn't look like it's hitting anything.
Vibration goes away once it's warmed up a little.

Aftermarket X pipe or cans?

If so it's probably hitting the reinforcement plate. Heat (expansion) moves things ever so slightly and stops the sound. The reinforcing plate mounts and X pipe alignment are tricky. I've had mine off several times--the last created the issue you have. Small tolerances IMO.
