I just purchased one of these and installed it on the box. Pretty much the same as everybody else with the borlas and such. It was very easy to install (only 30 minutes), looks great, and is still pretty quiet. Just thought I would throw some info up about it.

 

I just bought a Stillen Axleback for off of ebay and put it on this week. It looks like a nice quality product and fits the car nice. It has a nice sound and is only slighty louder than stock.
