2004 Lexus is300 Rattling

Hey guys, got this issue with my lexus is300. I immediately thought its a heat shield or a loose part, but had to think of the worst first. Its only under load, and above 2500-3000 rpms and stops at 4100ish rpms. If its full acceleration there is no rattle, only under 25%. Its been really pissing me off. I am thinking its ganna be a rod bearing. What do you guys think? It is a 5spd manual btw

where is the sound coming from? Issues like these are only really diagnose-able online with a good video to get the sound

Sounds like from the front of the car. I do have a check engine on the cad due to an o2 sensor. Could an issue like mine be due to pinging? Maybe?
