I wouldn't worry about it. The nut has just frozen to the stud, very common oa exhaust systems. You can call it a bolt now:p

Yeap just be sure and put a little anti-seize grease on the threads so it'll be easy to take out next time.

One of my exhaust studs on my 300 would come out everytime I tried to loosen the nut. I just cleaned the threads up, put some high temp thread locker on it and screwed it back in. Let the thread locker set all the way up, then spray your exhaust nut with PB Blaster and unscrew the nut. Problem solved.
