And before it’s said I’m not talking about my exhaust I’m talking about that rattle in the first 10 seconds also the exhaust is modified no resonators or mufflers

You have probably already checked was there anything in Ur door holders or boot, or did U leave anything loose in the engine ( I left a spanner in mine once 😂)

Yeah something is rattling for sure

I’ve owned an Altima coupe. There a bunch of rubber insulator/hangers for the exhaust. I would check to see if any of those are spent and need replacing.

I would also check your heat shield for your exhaust

Id left it slightly open but not fully so yh
