Some people had issues with vibration, turned out to be a difference in driveshaft components for 04-05 cars; all the issues were worked through with actp and I think everyone ended up happy, one guy that wasn't happy turns out his diff was out of alignment.
Here are results on a Z28.

Pretty good synopsis there. I don't really REGRET buying the driveshaft, I just feel like there were better things to spend the $1400 on.
