So this is is on my 93 roadmaster wagon I used to own . The exhaust was rotted . I bought a 9c1 Y pipe from rock auto . A 3 inch cat off e bay , 3 inch fake flowmaster welded muffler from summit. The last part of my exhaust is a rear dual set up I found on a very nice 93 caprice wagon. I haggled pick n pull down from 75. to 15. I have a really good muffler guy in fremont put it all in for me. I took some pics and thought I would share it. It had a great sound and seemed to improve performance.
