Rattling driving me CRAZY

[Barrier]

Alright so I just installed my new beautiful MAC H-pipe 2 days ago, and yesterday I hear this rattling.... it's a very high-pitched and fast rattle, like a thin piece of metal, maybe some sort of flange... and it's coming from around the starter. I plan to take a flashlight to it while someones revving the engine... but I was wondering if anyone could know offhand what this could be to save me some time and angry neighbors

did you replace the gasket on the driver's side header/h-pipe connection?

Or maybe check the studs...

Most likely an exhaust leak on the passenger's side between the exhaust manifold and the h-pipe.
