So I have a 2012 dodge 2500 5.7 Used,
I just got a new exhaust on my truck so while I was checking out the sound my truck cut off at 4000 rpms, is this from the stock gov? How do I remove that??

IIRC a tune can do it, but there is a reason it is there from the factory-to protect the engine

It does protect the engine. I accidentally floored my Jeep in park one time reaching for something in the back and it protected me from blowing the engine up. Good feature.
