Weird noise coming from back of motor

Been chasing a breaking up issue and rich afr problem for a long time now. I somewhat got somewhere on the afr portion by replacing the map which brought me from 10afr to 13-14 afr (mostly 13ish unless cold start). After changing the map I started hearing this weird noise. Now the only place im hearing it from predominantly is from the exhaust side of the motor. It doesnt really sound like an exhaust leak and the turbo doesnt have bad shaft play. Hopefully someone had experienced this before so I can pinpoint this and get it back on the road .

thanks.

That sounds like an exhaust leak.
