I finally got to installing my K&N CAI. I was surprised at how loud it actually is, I understand why others have removed other "CAI" systems. I have not had enough time to test gas mileage, but after one run with my standard city milage, and another on highway mileage it looks like roughly speaking 0-1 mpg better on average.
For the part you really want, the audio files. I used my digital camera to create videos, before and after. It is important to listen to the before because to me the before video sounds louder than the car really does, so listen to the before to compare how it sounds like your car. Then you have an idea of what the after will sound like in comparison to the real world.
The volume is about the same up to 2000 rpm. You notice it at 2500, and it starts getting loud at 3000+ I was expecting more of a sucking sound, but it actually sounds more like the engine being amplified.
Before installing my cat-back system, I have some sound proofing material I am going to put around the air box. It is designed to be under the hood, and is oil and water resistance. It not only decreases the sound, but also is a heat shield, which I feel will only help the metal heat shield of the CAI system. We will see.
I do have a Belltech performance computer that analyzes the 0-60 and 1/4 mile times, and it estimates hp based on drag, etc. You must do some 60-30 timing tests, provide its weight, etc. then it can calculate the hp. I have an area where I have tested the car, but I get varying times, and the average between stock and with the CAI is about the same, so I am not posting any noticeable hp improvements. As for feel, it is loud enough that if there are any hp improvements I dont notice them as the car gets rather loud over 3000 rpm. K&N has a dyno test for the R/T showing a peek improvement of about 7.9 hp. from 1500-3000 rpm the hp improvement on their dyno sheet is about 2-3hp roughly speaking so it may not be that noticable.
I am not trying to provide a negative report, just an honest review of what I have experienced.
The following are links to the video files I placed on youtube.
The following is a stock video of the car in my drive way.
