Sound coming from header

When I rev the engine in by 05 Balt base a sound that sounds like a small chain click clack come from the header. There are no leaks. Is this just the way it is suppose to sound?

Sure its not a leak? Check around the gasket on the head for burn marks

does your engine shake at all? does the sound go with the rpms? do you have any CEL's? because this is not an exhaust leak, this sounds way more serious than a simple fix.

sounds like the header-downpipe gasket is no good or the exhaust manifold gasket. Did you use the aftermarket gaskets or the OEM ones?

I bought a set of OEM ones for $20 total for both and never had that issue before. Most aftermarket header gaskets are garbage.
