nasty smelling exhaust
lately my car's exhaust has been getting progressivly stinkier. The exhaust has a few small leaks and is pretty rusty, so I assume the cat is pretty much shot. It's probably just the cat going, but are there any other pieces of emissions equipment that go bad a lot on our cars? I haven't really bothered caring up until this point, but inspection is up in a month. any thoughts?

the car is FAR from a pos, 83 S, original 12a 108k miles. Anyway, yes a new exhaust is in order, but I don't have money for that right now. I want a full Racing Beat and thats like $700+ since i have to run a cat. Anyway, I was just trying to see if it might be more than just a shitty cat, i doubt it, just wanna toss ideas around is all.

I'd check that the air pump is working, and pumping air into that cat.... but other than that, just get a new cat or a cat replacement pipe.
I'd start by getting a cat that will socket properly into the RB exhaust you want. Just get the cat and hodge-podge your exhaust system back into working until you have the money for the RB.
What alot of people suggest for places that have emissions testing is that you get a cat *and* a cat replacement pipe.. mount the cat when you do the driveclean test, and replace it with the straightpipe after for... *racing* (read: driving) purposes. It helps the cat stay nice and clean for your tests, and it frees up power if you get a cheaper, non high-flow cat.

If I knew anything about ******* air pumps, or 12A motors, I'd tell you.
I'm still learning all this emissions bullshit, myself. I understand pretty much everything else about the 13B, though.

but you can't run a cat replacement pipe, 'cause you have emissions testing.... and to test the airpump, I'd say just pull off the hose and feel if it's pumping a decent amount of air at idle...
