no, i didnt take a pic. But they all mentioned they drove it (3 mechanics and the shop owners wife) because they were quick to tell me how great the exhaust sounds and how the throttle response is much quicker than previous. They are good local people from a small town, I would like to assume. They had never worked on one of these cars before. where can i locate the detonation sensor? Isnt that the same thing as the knock sensor?
