Was claimed it was stock when I got the vehicle but I'm not quite sure. Its probably been a little over a month that I didn't notice until my friends told me it didn't sound stock. I also had a friend who owned a 335i w/ the N54 as well but his sounded nothing like this when he first got his.

Clip of my exhaust:

Is this truly what the stock exhausts sounds like? Also have a question if the camber in the rear of my car should be like this, but I will post photos later as it is nearly 1am where I live lol.

I want to say it could be a pe mod or pe exhaust

Its not loud enough to be an aftermarket type or exhaust, almost sounds like closer to pe exhaust

The exhaust does not sound stock, but the waste gate rattle does 😎

Have you looked underneath? Post some photos of what's down there, it'll be easy to tell what's stock, or not.
