New to the forum. Had an exhaust issue this morning with my girlfriend's car and am stuck at work trying to troubleshoot. Braided section of exhaust (I believe this is the middle of three sections between the downpipe and exhaust section broke. The middle section needs to be replaced and I am having trouble finding exhaust diagrams for this specific car. Could someone chime in and let me know if the $600 repair cost she was just quoted is a ridiculous price for replacing this middle section of the exhaust?
