Thanks again guys!
The exhaust is definitely louder at all times, but in a good way. While cruising it has a sustained growl that wasn't there with the stock exhaust, but changes to more of an Italian tone when revving it high upwards of 6 - 8K RPM. I can feel a modest power improvement, especially in second and third gear at high RPMs. In my opinion it sounds more like a Lambo now at high RPMs, although not quite as loud, yet at idle it sounds and rumbles like a muscle car.
