Does this sound normal?

2015 Mitsubishi Pajero NX 250k May be hard to hear but it seems to run loud and vibrates quite a bit although it’s hard to see. I have had it inspected and was told it’s normal for this engine (4m41) however I’m not convinced. It has a full service history half its life at Mitsubishi yet no codes, no leaks, drives well.. I was told it could be exhaust gas leaking past the injectors. Thoughts?
