Knocking sound coming from engine

What's up guys? My car has been a problem child for me and now after i got it running pretty good this happens.
I dont have headers but it almost sounds like the sound is coming from the manifolds. It only happens at low RPM and my performance sux

Since we cannot hear the sound, can you be more descriptive? If it sounds anything like this, you will be rebuilding the engine.

Yeah that is an example of a bad one, but your noise could be similar, but not as loud and be from the same cause-bearings.

does it sound like a ticking? could be an axhaust leak or perhaps a lifter problem or valve adjustment issue

"It's the engine" is pretty vague.

What part of the engine?
