The engine temp is the same, the cat in the pipe is the problem. I installed a gutted cat I got from fleabay and the diff is night and day. My right leg is happier now. Do it and you wont regret it.

Collected tuning data (including engine temp) both with and without cat...no difference in engine temp.

No temp did not drop but that ball of heat right at the CAT may have improved.
remember how a CAT works it gets hot very hot to burn off pollutants .
