I have this weird noise coming under the engine makes a thumping sound kind of I don't know if that's normal for the 3v but any help would be appreciated it.

Hard to tell from video if I hear anything out of the ordinary.

Is it more pronounced by the driver side wheel well?

Sounds more under the driver side but at the same time I'm thinking that maybe it's the mufflers I installed especially since I'm catless, I just never heard a sound like this before

Agree and to me, only sounds like normal exhaust backpressure.
