I believe the anniversary is geared to the 68mm TB where as the 996 is geared to the 74mm.
You will: be able to start the car without depressing the clutch, reducing engine wear;
not have to worry about post cat o2 sensors/codes; loose the ability to monitor one cam shaft for deviation from ideal.

If it's no longer monitoring the post-cat O2 sensors, does that interfere with the IM testing? In my state (Utah) it's a plug- in test, not a sniff up the exhaust pipe.
