Do you still have the stock mid pipe on there? I can hear the shorties. It really does give it a slightly deeper tone. I see you went with the chrome. Have you noticed a difference in intake air temperatures with the new shorties? I ask because I went with the AEM CAI and when I sit at a light I see the temp rise quickly due to the tube being metal. Ceramic might be the way to go for me.
