I thought I read that 2009 turbos did not have coolant pipe issue as Porsche had it rectified?

All GT2s, GT3s, their variants, and Turbos pre DFI are subjected to a potential catastrophic coolant pipe fitting failure. So, yes, even the 2009s which uses GT1/M64 block are subject to this problem.

This leak, while not very common, is more likely to occur with age as the adhesive is subject to heating/cooling cycles. While the number of failures is small, a leak on the track can potentially lead to a catastrophe. Several have reported that their vehicles could not participate in track events because the tech inspectors would not allow an "un-repaired" vehicle on the track. The NHTSA did an investigation on the adhesive failure and decided that this problem did not warrant a mandatory recall. They completed their investigation about 18 months ago.

This leaves us with aftermarket welds, pins, or to thread the fittings a la GT3 RSR:

Which means it will likely occur again some day.

Where did you buy the RSR part? Also, there are 7 total fittings on a TT so that eliminates 3 which I am totally for threaded fittings just wondering the normal part number is 996.106.161 5R They simply thread the normal part and put on fittings?
