Is ~$1100 reasonable for a replacement exhaust system? on 2000 Toyota Camry

The flanges on my exhaust system are very rusted. In fact, my muffler has just very recently disconnected from the rest of the exhaust system. My local repair shop has told me that starting from the exhaust manifold on back will need to be replaced. Is $1100 reasonable for that? This includes the catalytic converter and O2 sensors I believe.

sounds a little high ask for a written estimate to see what they plan on replacing
get there est in writing and get a 2nd opinion
