Crushed exhaust is a problem. Try breathing with someone closing off half your throat. It is similiar.
The jb weld is temporary fix at best and is not a permanent fix.
As far as being rough, it would have to be determined by a shop to see just how much damage you did.
Do you have collision insurance on your car? This would be covered if you did have it.
