So when I had the car on the lift last night, I noticed that on the left exhaust pipe, about halfway down the car, there is a dent on the bottom of the pipe facing the ground. Like the car was sat on something and the pipe bore the weight. It almost looks normal though. It's a small, flat indentation and then its evenly flattens out as it progresses back towards the rear. Imagine spreading icing with a knife. It's about 3 inches wide and maybe 5 inches long. I'll take a picture tonight at work but there's no scraping or anything. As I said, it almost looks like its suppose to be there but I can't imagine why. So, normal?
