Replace Catalytic Converter - cost? on 2001 Volkswagen Passat

I purchased a 2001 Passat with 62k. I just spoke with someone who owned another 2001 Passat and told me she got a quote of $6000 to fix replace her Catalytic Converters. Is that right? The price seems out of range with what I would expect.

Asked by for the 2001 Volkswagen Passat
Those comes with the front pipe, both (Bank1-2) cost about $ 1,700.00 and 3-4 hours of labor (could be more if fasteners are corroded)
Thank you!
