Default rattling sound during acceleration

hi i cannot seem to find where this issue is coming from. it happened after i swapped exhaust and i thought it was exhaust leak but i have done everything you could think of with the exhaust to try fix the issue. I've tried wrapping the pipes where they join and get clamped down, and also jb weld, but still the issue exists.

i hear the rattle type noise kind of sounds like a garden sprinkler during acceleration. I cant reproduce the sound if the car is standing still and just rev it. nor is the sound present while cruising. i just hear it when accelerating and near a wall or parked cars usually make the sound more audible.

what else could it be if its not an exhaust leak?

What does a pilot bearing rattle sound like? I only get this noise while in gear and moving.

im wondering if maybe its your heatshield near the airbox. If those small screws are just the tinest bit loose it will vibrate like the way u are saying. They are kinda tough to get too if the engine is warm cuz its so close to the cat. Might check that also.

so i have narrowed it down to the front driver's side. but i removed the heat shields as a test and the sound is still present.

do you know what a failing turbo sounds like?

like a dentist drill. IF its near the wheel it might be the spring retainer that holds the caliper in place. u might hit it with some wd40 and see if that stops it. just trying to give u solutions that are cheap before you look at a big bill. . .
