I have a 1995 Saturn Sc1 recently put in ditch. The car being plastic there were no body damages, though the rear passenger side tire came off the rim, a spare was put on then later the origional tire. The car was pulled out of the ditch with a tractor, and im afraid that the tractor or the initial impact may have ripped in half a part that connects the exhaust manifold and the cadalytic converter...please, does anyone know what this part is and how much it would cost to fix...this would be a great help because i have just begun driving and know very little about cars....also the car leans to one side could this just be the tires or the axils...or does it possible just need aligned?...please help very confussed
