I got my FI exhaust installed on Wednesday so I was able to finish my head to head comparison video. This is shot entirely with a Flipcam so the audio isn't perfect but it should give anyone who's considering buying one a very good idea of how the sound of the car will change.
So far, I love mine! I don't even want to listen to my radio any more.
