Talking Safe to flash Bootmod3 MPPSK Tune without the actual Exhaust?

I’m cheap so I’m thinking of making a ghetto “MPPSK” exhaust for my 2019 440i where I delete the resonators, and install a Remus Axle-back exhaust. Voila, a ghetto MPPSK Exhaust system for only $1400.

With the above exhaust setup, I’m curious if flashing my Tune with the Bootmod3 version of the B58 MPPSK tune will be “safe” for the car? As in not cause engine problems down the road? My logic is if all that the MPPSK exhaust is is two straight pipes with a performance muffler, my setup would scientifically be the same thing.
