E34 1992 Touring - Exhaust System questions

[giantleap4]

Hello - I'm a new Bimmer owner. Just bought a '92 525 Touring wagon. The exhaust system has some holes in it is sounding a bit rough. What are my best options for a cost effective replacement/repair?

Also, if I went to the junk yard, which other E34 models use the same exhaust system that I could cannibalize?

Huge appreciation in advance for any actionable intel!

Preferably one from a 91+ 525i

You should be able to find a rust free catback from a cali yard pretty easily. Under $40 last time I checked. Also try CL
