1993 possible buy

Here is the Y pipe I used $47.79 from Rock Auto and they still have them http://www.rockauto.com/en/moreinfo....sn=445&jsn=445
I'm betting a farmer could find a way to swedge the ends to fit a 93 manifold. I also got the exhaust kit which is not out of stock and a CAT
Here is a 93 Y pipe by Walker on eBay $96.70 http://www.ebay.com/itm/Exhaust-Y-Pi...5XVHzg&vxp=mtr
Here is the Walker site if you want to look up for your own stuff it has a where to buy locator which may mean you can get them ordered at a local store. http://www.walkerexhaust.com/products
Edit- I meant to say the exhaust kit IS out of stock that word should have been "now" not not

What you can do is take the 89-90 pipe, or a 93-96 pipe, and have a competent exhaust shop bend one for you.
Bonus, a really good shop can mandrel bend it, and get rid of those crush bends.
That's good for a bit extra flow all by itself.
(If you still have the 93 Y-pipe, but it's in bad shape, they can match it instead.)

When I replaced my clutch Aug 2015, I replaced my y pipe on my 93, and there was none to be found. I promise, I made lots of phone calls, it is discontinued and they are long gone.
What I did was get the 94+ y pipe which is smaller, then went to the local exhaust shop, had them make up some 2 1/2" socket flanges. I cut the 2 1/4" off, bolted up the new flanges, and slid the y pipe into them. Tacked them up, took it down and welded it together. It isn't the prettiest (2 1/4" pipe slid into 2 1/2" pipe, weld filling the gaps) but it works fine.
Then for the other end, I used a 2 1/2 to 3" adapter slid all the way up to the o2 sensor to make sure I didn't add any length to the system. It's been like that for over a year, and it works. Power isn't an issue to me, 5hp doesn't matter to me, so it works, and it doesn't leak.
If power were the real plan, I'd have gone header and duals.
For some exorbitant amount of $ the muffler shop could have probably made me a new y pipe the right size, but it just isn't worth several hundred $'s to me.

I had thought I "knew" that all exhaust of gen 1's before 94 were the same. Anyway I contacted Walker and they do not make the 93 Y pipe. So if you actually want to go the way of putting the 93 exhaust manifold on your 94 you will need to find a different manufacturer, get a good used one, or a new one made at a muffler shop.
Edit- The 94 Y pipe they sell is still much bigger than the OE 1 1/2" that was on mine.

The manifold needs to match the exhaust system; it's not a "Swap just the manifold" type upgrade.
Check the injectors; somewhere in there they changed the injector flow. Not a big problem; keep the ECU with the injectors and you're still good (so it uses the proper tables). I THINK they went with BIGGER ones in 1994; BICBW.
(And it's not that much bigger; it's within the auto-correct range for the ECU, but it takes out your adjustment for running changes.)
