So I finally had my Flowmaster American Thunder cat-back system and K&N cai installed over last weekend...and holy chit is it loud! I'm extremely glad I didn't go with the Outlaw... I would have definitely been kicked out of my neighborhood 
This one is perfect, but even still I have to be cautious in the morning when I leave for work...it's extremely noticeable when it's warming up. I'm not sure if it's the addition of the cai, but it seems much louder in the cabin than I would have imagined when watching the Outlaw video. It's definitely loudest between 2-3k, but man oh man does it sound GOOD! The black tips are awesome, the exhaust is awesome, and outside of it being a lot louder than I expected in the mornings, I'm 100% satisfied with the purchase! I'll try to get up some pics and a sound clip soon.
