I found this on the underside of my saab the other day. It is in the spot where the catalytic convertor should be but when the car runs it smells like there isn't a convertor on it. I can also tell that is definitely not stock on the basis that it says TOYOTA on the side of it. Also on the opposite side of the can (not in picture) it has the number 93 on it. This thing is really bugging the heck out of me because I don't know if it will pass the emissions part of the MD state inspection. ANY INFO IS GREATLY APPRECIATED.

PS: if anybody needs anymore pictures of it I will gladly get them.

That is what we in the automotive industry call a muffler. ;)

THE 80 / 20 rule ...

From what we can see ... Looks like a Muffler ,,:eek:
From what we know ( mufflers usually found connected to exhaust pipe ) It could be a muffler .... :eek:

I guess the final test is to run the car ... and brush the inside of your forearm against it... ( please dont DO THIS ) :nono; if this results in nasty burn to tender skin ..


YEP .. MUFFLER ...

But why would you want ot put 3 mufflers on a car and no CAT? That makes no sense because in the US all the states have emissions laws and this car has to pass that test since it's a 93' and I garantee that the lack of a CAT will fail emissions in everystate. Whch makes me think about the person who we bought the car from. When I got the car it had a New Jersey inspection sticker on it along with tags. But I can't remember if the tags had expired and needed to be renewed. So this car could have been driven illegally on expired tags:eek: . No worries though, slap a new CAT on it and take it for inspection.

- I don't go through emissions certification in Pennsylvania - which is part of the United States - emissions tesing here is on a county by county basis - determined by population density - so your supposition that emissions are universal and mandatory is in error.

Further - if they did only a visual inspection, the presence of a can in the correct location just may be enough to fool an inspector. If they base emissions testing on visual plus CEL (check engine light) - again - if you're not throwing a CEL you'll pass. The CEL is a determining factor in some Pennsylvania counties - if you're throwing a CEL you fail. There is an obvious way around this if you've a mind to do so - although the CEL light DOES need to come on at initial startup - it just cannot persist - some people do use a simple timing circut on the bulb.

As for tailpipe testing - many cars can pass the tailpipe test without a cat - it depends on the state of tune of the vehicle, the engines health and what standards you're measuring against. A friend of mine in MD passes the tailpipe test - with a gutted cat.

As is normally the case in this great nation of ours - nothing is simple.:cheesy:

As for why someone would do this - no doubt they had a leaking cat or a broken flange on a pipe - had a toyota muffler laying around - determined that the inlet and outlet diameters corresponded to the bits of pipe left on thier 900 exhaust system and decided that bodging the fix and then selling the car was cheaper and easier than doing it right.;)

Thank you for pointing out my error. I will correct that in the future. I thought that the emissions test were the same throughout the state. But I knew they varied around the country.

The US does need to simplify its testing and tighten it up. Shows how much the US cares about its cars.

I wasn't trying to be an a*s - it just happens - apologies for any offence - what I typed was as much out of frustration with the variablility of regulations in the US as anything else - it's absurd. You SHOULD be able to make a universal statement like "emissions tesing is required for all vehicles in the US" -

Of course I, living in PA, can drive and chat on my cellphone, you, living in MD, cannot and if I drive to NY I cannot use a hand held phone their either while driving - the variability is foolish and confusing.

Anyhow - back to your car - hopefully when they installed the Toyota muffler they didn't whack off the catalytic converter flanges - or you'll be looking at replacing the front pipe (from the manifold to the cat), the cat and the center pipe (from the cat to the first (correct) muffler - if you're in Northern MD I can PM you the contact info for a shop in Abbottstown PA that specializes in Saabs - and who happens to have a warehouse of parts.

I have a box like this on mine instead of cat, here under g/stick. it is a saab box though as fitted on the earlier turbo cars(as my down pipe has had it, so will do for now)gives some extra bhp :D as apparently the red box gives the extra bhp that the cat reduces, which is?? the same as the 3 box system and standard turbo box
there is a thread re exhaust done in the last week which i started to see what the UK mot laws were concerning this change over and the response was as your thread, would probably not pass mot test, but put a cat on for test then take it off after and you will have extra bhp back.
i don't think it's illegal to have them, as it's an exhaust system and not noisy, bit like the motor bike's putting racing exhaust on for more bhp.
