Various parts of exhaust system have cracks. Does the whole system need replacement? on 2001 Audi A6 Quattro

The supporting structure for my exhaust system eroded causing the middle of the system to drop almost to the ground and caused cracks in various places. Is there any way to repair this without replacing the complete exhaust system? Can only the faulty parts be replaced? Can the support structure be repaired?
Thanks ray-audi

That can only be determined by inspection to see what is needed and what can be saved. Get some different estimates at qualified exhaust shops.
