Installed the new exhaust, same issue.

Edit*

After driving the car and logging some miles, I can say it is actually better then the other exhaust. It no longer has the same leaky sound after I have been driving it for a while. It does still have a slight hiss with the valves closed in park at idle that you can only hear when standing behind the car. I can live with that so case closed.
