Ok so I bought some Audi Exhaust Tips from the dealership. I tried putting them on but when I slip them over my stock tips and try to tighten the three screws, the three screws don't touch the tail pipe at all. They are not long enough. If I just try to tighten the screws while the exhaust tip is over my stock tip, then the screws stick out too much. Am I losing my mind? The box and dealership say its for my car. This should be the easiest bolt on mod ever. What the hell is going on? I thought all the tail pipes where the same circumference for these dealership tips.
