Exhaust leak crap shoot question
So I drove from Denver to Vegas and upon arriving I get gas and as I pull out with the window down I hear what sounds like an exhaust leak/tick. You can hear it only under part throttle acceleration and only with the window down. The funny part is the tick in not there until the car is fully warmed up. When the car is cold it's silent.
So now for the crap shoot, what is your guess on where it is from?

It is a tick that sounds just like an exhaust leak but only when the car warms up and only under acceleration. I'm thinking manifold or somewhere close to the engine.

A bunch of TT's
The Oem manifold nuts do loosen up over time. But that's more of a hissing when it gets worse right around the headers. You could prob try having a look around the manifold/DP for any blackish leaks on the ex material.

That could be a possibility. It sounds like a hissing under more throttle and a hissing tick at light throttle. I'll have to check those.
