Been having this weird sound recently that I notice when i started my car up. Can’t really hear it from topside engine but towards the bottom, near the exhaust sounds like some type of knocking to me. Anyone have any idea???

Possible cracked lower header mounting bracket. It is impossible to see unless you flex the header outward to reveal the crack.

I will def try to check that out. Its a sound that doesn’t go away as gets faster when I rev the engine.
