Catless DP's might fly under the radar on emissions if you bring in the car fully warmed up so that the secondary cats are doing their job. The one's in the DP's are mainly just for when the car is cold since they warm up the quickest.

I would be a little careful going DP's though if you are thinking of getting a tune as well, unless you are absolutely sure you do not have progman 29.2, because you will be close to the code trigger limit then. If you are sure you don't have it though, there shouldn't be a problem.
