The pops and cracks are still there but it is louder. Sounds great with the window rolled down and still fairly quiet inside the cabin.

Thanks. The dealer did the install and one more local forum member, Protious, will have his done by the dealer by Monday. They are catted which is why they were able to install them. They charged me for 6.5 hours of labor which is about what Nate said that they would take.
The result is that the throttle tip-in is what is much easier to do from a dead stop. Now you can hear the exhaust and easily tell when you are having wheelspin due to the revs changing tone. Breaks the tires loose easier now in first, second and third. Very, very happy with the results. As I stated before, sounds a lot like the raspy exhaust on the olders air-cooled Porsche Turbos. I will try to do a video/sound clip today or tomorrow.
