crackling noise from engine

[SteveO2569]

hey guys, when i accelerate i can hear this crackling noise coming from somewhere in the engine and as my rpm goes up the noise decreases, u can especially hear it when my engine is cold and seems to get better as it heats up but just wondering if anyone had any clue to what this might be


thanks

It may be an exhaust leak. Can you explain the crackling noise in a different way?
