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.

the MPPSK tune is definitely safe for your car as BM3 gives u the copy of what bmw would do if u had bought the MPPSK. anything beyond the catback will not give any noticeable horsepower gains so u have nothing to worry about

Nah I totalled my last 440i on stage 1 because I spun out and crashed into a tree. Floored it and started going sideways LOL

No you don't. Still smaller diameter pipes

Yes, it's safe. You will have a similar, just inferior, setup
