ROLLED: Can I ask if you have an aftermarket cat, or headers? And have you ever been hit from the rear?

We took the time out this morning to take my exhaust off and to put a brand new Spec IV on (very nice looking exhaust BTW! I'd say it looks nicer than my dual!) and the exhaust is not hanging as low as yours at all. AND my car is lowered quite a lot. This is leading us to think that your mechanic has installed it wrong OR you might have been hit from the rear and something has been bent, forcing the exhaust down lower OR you have an aftermarket cat/headers which have forced the joint to be lower.

Please reply with more facts. Our pics of this install will be up shortly.
