Just wanted to see if people had a guess on what the problem could be before i find out. Ok so iw as cruising around tonight and went over this litle bridge thing which was really close to bottom of car (its lowered). I was fine going in then on way out i felt a really big smashing sound and now i got an exhaust leak. I have the GM catback too so im hoping it jus pulled off after caralytic converter. Any ideas before I start looking and find the bad news.
