'97 V6 Cabrio exhaust help

[Ozone]

The OH's 2.6 Cabrio needs a complete exhaust. Took it to Kwikfit today (i know) who can't find the part numbers for the sections and think that it's the original exhaust (done 185k) which they think is a largely complete section where as the newer ones are in 4 pieces. Can anyone make any recommendations as to where to scource all the sections including cat? She doesn't needd a sports exhaust or anything fancy.
Thanks.
