Welcome to the site from Ontario. Nice clean Cutlass! Cool looking interior. Lots of good folks here. I'm sure you'll enjoy it.

Did you also throw in a posi into your diff? I am running on an open diff right now and so I guess I'd have to get steeper gears and a posi. I will check out this website and I'm hoping shipping won't be too much. A set of roush axel back mufflers for my 15 gt cost me about 900$ cad with shipping. Good grief...

I did put in a used Auburn posi from a Camaro. Budget was tight when I did it. If i were doing it now I probably buy a new unit and upgrade to 28 spline axles at thr same time.
To me the main upside of the GN exhaust is that its 2-inlet and 2-outlet with a single muffler in the stock location behind the rearend. Probably not a real noticeable prrformance gain but was worth a full second in the quarter for me. Still slow

It has a distinct muscle car rumble without any drone like a lot of the performance mufflers. Just personal preference. No need to sound fast it it's not.

Nice looking Cutlass. Welcome aboard. That interior is one of a kind. I do not think that was stock?
I'm looking on rockauto and I'm not sure where I would find an exhaust kit. What parts would I need to install a dual on my car? I have no preference for x or h pipe but I don't want a y to à dual cat back.

Welcome from Melville, Saskatchewan. I believe that is the rare Aztec interior. Price out a 2.25" custom dual dual system at your local muffler shop. If you keep your stock axles, get the Detroit Trutrac posi. I just upgraded to the Yukon spider gears with my 3.42 gears. The stock ones are soft and tend to explode. The 2004R with a 2000 or so stall lock up converter will really wake the car up with 3.42 gears and pull down great mileage. The dual exhaust helps as well. With stock height tires you need the black and green gears in the trans. Use the TCI lock up kit. In my 88 with a dual exhaust Olds 260, 2004R and 3.42 open I get very good town mileage and got 26 mpg imperial last highway trip on a windy fall day, shooting for 30 mpg. If you drive like a normal person 25 mpg imperial should be possible on the highway. The Hooker Aerochambers sounded amazing under my 88 but were on the louder side.
Muffler, both pipes going over the rearend into the muffler, both tailpipes. You'll have to have a muffler shop do the pipes from the manifolds back to the rearend.

Looks like this when it's done.
I hope it's okay that I put this here. If you don't want it to muddy your thread just let me know and I'll delete it.
