tick/rattle when driving, 4.6

A couple weeks ago i was driving my p38 for a couple hours, and it developed this rattle/tick noise that I initially overlooked just assuming that it was my exhuast leak patch on the back of the pipe that I sealed. However that wasn't the case. The sound is coming somewhere from the engine it seems to be the passenger side of the engine and it is driving me insane as I take much pride in driving this car and it's my daily driver. I do have issues with the exhaust already as it is really worn out and rotted in certain spots, but from what i've seen for similar cases it's either the downpipe or exhaust gasket/manifold. Anyone have experience with an issue like this? The car is now louder when driving and upon acceleration the rattling noise gets louder and more and more apparent. I can absolutely link a video of the sound if needed. Thanks for reading.
