I don't have a code reader, the error message is right (and now left) tail light malfunction. As I mentioned, it happened the first time on the dyno (after I had had the current set up for a while) I assumed the small closed space, which amplified the exhaust note significantly, increased the vibrations as well causing the problem.

I guess in reality, I don't really KNOW that these things are releated. Just seemed logical. Anyway, any other thoughts are appreciated.
I've had those codes pop up, even though the lights still worked. Never thought it had anything to do with the exhaust. I eventually pulled out the light bulb housing (accessed from the trunk), wiggled the bulbs to make sure they were snug, unplugged the wiring harness and plugged it back in for the same reason, and have never had a problem since.
