Tick inside Exhaust? Valve Train?

First off, the engine is a 360, x heads, air gap intake, holley sniper injection, cheap hedman headers, mild cam, stock rotating assembly.
I have been trying to determine the cause of this tick that I have been hearing when driving. The sound is present at idle, cruising and deceleration. It goes away when accelerating and when I go around a left hand turn/bend at speed and it is almost amplified going around a right hand turn. I was thinking there is an exhaust leak but the turning symptoms seem kind of odd to me?
The sound isn't very loud when looking in the engine bay, but the sound is louder around the header collector when you're under the driver side. I don't see or feel a leak at the header/pipe flange and it sounds like it is inside the pipe right at the collector. Has anyone experienced something like this before? Is it the cheap/poor designed headers causing this?
