Just got this not very nice rumor news. Apparently, 991.2 GT3 RS from production October 2018 Will have less power. More restrictive exhaust system acquired for new regulations is to blame. 

Ok, this info is from my side taken with grin of salt but... 

I would think this would make it more socially responsible and desirable. The over powered polluting version will be worthless on the used car market.  Can’t wait to see the 992 Econ numbers. (Do I need a sarcasm warning at this point with you guys?)
