Testpipe installed!
After procrastinating for a couple months about getting a testpipe to replace my worn out catalytic converter, Invidia came through once again and my exhaust is nearly 100% back pressure free after today's install of a testpipe. 
For those who are wondering, the sound is completely different. Most of the exhaust noise heard from the inside of the car is what you hear coming out the back, there is virtually no interior exhaust noise. The Invidia exhaust with a cat is rated at about 108 dB at WOT. Without the cat and the addition of a testpipe, it goes up to 114 dB at WOT. And you do hear the difference!!! It is intoxicating, best $100 I have spent on that car!
