the engine sounds normal (to me at least)
to clarify, the first clip is of a noise that only occurs when under throttle it sounds almost like marbles in a tin can and it comes from under the passenger side footwell
the second clip is of a popping noise that seems to be coming from under the drivers side of the car, it starts happening after the cars been on for a couple of minutes or so and persists whether I'm idling or driving
does anybody have an idea as to what these noises are? coolant looks good, oil looks good, i dont have smoke coming from my exhaust, the car still has power and drives normally, idle is at around 790-810 from a cold start, new COPs, fuel filter, spark plugs, etc
maybe pre-ignition? loose headers or hangers?
