I had an AEM CAI and ART Pipes installed this past Friday. What a difference in every way. The performance factor is very noticeable according to the seat of my pants gauge. Better throttle response and pull through all gears and the sound...well Khoi said it best, its BAD A$$. This is an in your face setup and should not be done if you want to fly under the radar or be politically correct or want go unnoticed (kind of an oxymoron in a Nismo
). There is an increase in rasp and drone at the same RPM points so beware if you have sensitive ears. I'm going to have fun with it for now, but contemplating a new exhaust to get rid of the rasp and drone. Will get the car tuned when I make up my mind.
