Good quality products as always from Injen have yet to install and use on the car but seems pretty straight forward.

The step by step installation guide was perfect. Took about an hour to get it installed. There's a noticeable difference in sound. You can start to hear it around 3k rpm and it sounds amazing at 4500. The quality is top notch and installation was a breeze. I'm extremely happy with this purchase.
