I know that this has been discussed before but I am looking for replacement exhaust from the cat back that matches as close to original as possible without a lot of modification. If anyone has any NOS mufflers/tailpipes I would be interested in them but I know that is a long shot.
Cat back exhaust for 83 hurst

That's going to be tough to find, I think Walker used to have pretty close system available but sure it's long since been discontinued.
Pypes has some options that look pretty close, but won't have the OEM crushed edge style mufflers/resonators, but they seem to have the OEM like dual split post CAT pipe that looks close.

I'm sure someone in this community has a lead, or something else that might help you out.

By the time I started my project Regal in 2015 all of the Walker exhaust systems for Olds factory style dual exhaust were discontinued but I was able to piece together an exhaust from multiple vendors, I was able to pick up a Y pipe, mufflers and tail pipes of the last remaining stock so I can't imagine trying to find that stuff 9 years later.
The mufflers were the hardest to find and they are very small and there were no aftermarket equivalents that fit in that spot.
This is back when I was doing mock ups

Here's some parts catalog illustrations, maybe you can have local exhaust shop fab you up something that won't be original, obviously...but have the same basic design post cat.
The Olds VIN 9 muffler was the smallest I’ve ever seen. I can’t recall the dimensions but they’re baby mufflers. 11 or 12” x 4” comes to mind but I could be wrong on that. Walker did have a good replacement while they lasted though. The y pipe wasn’t the same though as Walker just tapped off the extra pipe instead of angle cutting both pipes and welding them together to emerge from sort of a cone. But it fit ok.
Looking at those pages reminds me that I have every single part shown as NOS. It’s one of the few ultra- complete systems I have in my stash. Even the GM fasteners.
Any chance you want to part with any of the items? Unfortunately I think I know the answer 🙂 . If you are please let me know. I have the originals from mine (even have the crinkles) and they are probably usable but they could definitely use an upgrade- getting pretty rusted around the muffler intakes. Since I took this frame off I wanted to make it where I don't have to touch it again for many years. Like you said it is the mufflers I am having problems with any local shop being able to come up with.
The nos pipes over the axle don’t have the crinkles. They were bent by sliding shoe type of bender. The factory pipes had crinkles because of high volume production methods necessitated that. Unless you had a custom set of pipes bent up using a special shoe to induce crinkles, you’d be stuck with the smooth bends. Anyone that says differently is full of crap. Every NOS set of tail pipes I’ve ever seen are the smooth bend style. And you’d be right in that they aren’t for sale. Sorry. Wish I’d have bought more while still available.
These are the factory originals. I've had the car since 83 and it still has low miles (Its #14) so nearly everything is original except the tires. I agree with you, all NOS have the smooth bends and I have no problem with that but I am having trouble finding any Mufflers(resonators) that are close enough without modifying the Y-pipe also. I guess basically I am looking for someone with a NOS set. I may just have to put the originals back on but with everything else restored it would be nice to have some nice looking exhaust. Since starting the restoration I too have often looked at those pages in my parts book and wished I had bought some a while back. In hindsight though when I stopped driving it they were in ok shape but 20 years of sitting on damp concrete un-driven does bad things to the underside. Thanks for the help .
Thanks 383, I have the parts book and the original pipes and mufflers that I can probably have fabricated by the exhaust shop I use for other vehicles but I am trying to keep this as close to original as possible. Thanks again
