Also the exhaust goes straight from the turbo to the stacks doesn’t go through the filter at all so I’m not sure if that has been tampered with at all.

As to the exhaust the only thing important to the engine is that it flows freely (no restrictions) and doesn't reflect heat back to the engine. If you have straight pipes then that should be fine. On the other hand, if you want it to look stock then the DOC, DPF and SCR cans all need to be completely empty inside. Many places leave the original exhaust untouched or only drill a few small holes through the material. That is what leads to some big problems down the road.
