Have you had the car hot yet Mike? My exhaust gets louder when I've done a long cruise or hit the track. Your volume will go up when everything is hot.
Give it at least a month of solid driving. Toss in the carpet in the back like I did and you will get used to it. The carpet reduced the noise a little bit. However, top down, it won't make a ounce of difference :P
Would love to hear it. Did you guys meet up today?
