I love it! Performing way better than expected. My exhaust sound is better, I definitely feel a difference in power, I don't need to tune therefore I don't lose my warranty, and I get about 2 mpg more. All this for under $180 (bought it on sale black friday). It's a no brainer.

Only annoyance is that you have to drill a hole in the box to hold a hose, it is however optional....
