Default What is this noise coming out of the LT collector?

I was underneath my car today and I heard a tapping or clicking sound when i was checking a leak. Its coming out of the collector on my long tubes. Its not the exhaust, but clicking lol. It sounds like the valves opening and closing, but i want to make sure. The drivers side bank is louder than the passengers side bank. So is it the valves or or am i just paranoid?

Clicking and pinging sounds are normal from LT headers. The long tubes kind of amplify various sounds coming out of the engine.
