Anybody have the Fast Intentions Non-Resonated Test Pipes + Stillen Catback exhaust set up on their g37 sedan? How does it sound? Performance?

I have the stillen system installed already and just ordered the test pipes. Just looking to see if anyone else has any thoughts.

I know this thread is old but if you are still wondering or anyone searches later. The test pipes will cause the exhaust to be much more raspy. You will get some good performance out of the test pipes but usually I recommend a tune to get the most out of them.
