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

. 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.
