Heh, I would say 13Bs are more "true" dual than V block motors since they collect 3 or 4 exhaust ports into one pipe first. Can't get more true than one pipe per cylinder (rotor housing in this case).

Seriously though, why would true duels have anything to do with passing emmsisions if you throw a cat on? Emissions may get tougher, but they can't be tougher retroactively. It would be grossly unfair to do so. The odd person has done it without cats (although I don't know if specifically with the Mazdatrix exhast, but I fail to see why it would be any different).
As for emmisions being stupid, how many people like not seeing the sky in the summer? How many people like the increase in people dying from repriatory problems? Other environmental problems?
J/K J/K. I was actually just up there this week.

The easiest way to get cats into a dual system would be to have the whole thing custom made. It'd probably end up a lot cheaper than buying an off-the-shelf system and then chopping it all up to fit the cats.

PA's is as such: "any car driven less than 5,000 Miles per year, as verified by the inspection sticker, is exempt from emissons testing requirements" ans that includes the visual. The catch is, you must own the car for one year prior to the exemption, presumably to verify that you drive it less that 5k in that year.
Hmmmmm... cable driven speedo... you figure it out!!

The only thing that the current regulations are doing is generating more mony in the pocket of the states and the inspection mechanics. They give the politicians something to crow about and say that they are doings something, but, in reality, its just a sham. Meanwhile, lobbyists for the power companys are working on getting the clean air restrictions for the big power companies relaxed. The teamsters obviously have a good lobbyist, because somehow they've convinced the EPA that the thick black soot you see being belched out by tractor trailers every day isn't harmful for you to breath.
You want to cut emissions from cars... you have to limit the number of vehicles on the road, or limit the amount of fuel burned by those vehicles and every jackass keep up with the jones's sumbitch out there in their freaking lincoln navigators or cadillac escalades are just adding to the problem. Add to it the fact the the oil companies are blocking every attempt to make high MPG vehicles that they possibly can, and i think you'll start to get the picture. (I have seen some of the patents.... if you think that the hybrid electric cars like the prius get good gas mileage.. you sould see what they SHOULD be getting).
Sorry, but this subject really pissed me off, cause i work for the people who are pushing this bullshit down our throats and i KNOW its a freaking con game.

my idea: 2 GM electric smog pumps (these can be turned on/off by preset on haltechs -- not shure how otherwise to be honest) and 2 three-way catalysts. you might be able to split the air from one, but the more oxygen you get to those cats, the more likely they are to do their job.

Personal note: Prius gets crappy mileage. I can easily do 100 MPG + in my Insight...Screw gas, electric is the answer. The current "hybrids" are not even hybrids...
Now back to the real topic...

YearsOfDecay - You've got some excellent points. I'm glad to hear it from someone on the inside. I am plenty aware of how politicians are using it. The general public is stupid enough that IMO politicians could get away with even less. At the very least it gets people use to having to alter their lives ever so slightly to make a change in pollution. I think it makes some difference on smog, etc. so I will continue to support it and a lot of measures that have yet to be taken.
In Ontario we started to crack down on transport trucks, but our pollution is the 3rd worst district out of all US states and Canadian provinces!

why not just swap the old exhaust system in when it's time to get smogged? that's what i do.
granted, it's a bit harder to swap out the header and exhaust manifold, but it's only a few hours of work if you take your time.

Now then..... as to passing with True Duals. You can do it with 3 preset conditions. 1) you are taking a 5-gas sniffer test, 2) you have a Haltech and 3) the mechanic doesn bother to do a visual test, or the state laws only reqire that you pass the 5-gas. You just lean the car out and tune it for max efficiency and hope the teck doesn't give it any boost..... I've seen it done!! Me, I'm going for the 5K exemption!

How come no one has suggested that you fabricate a dummy cat? How about a factory cat that has 2 holes cut in either end that has been punched out with straight pipes running through the middle. Just weld up the middle holes. Problem solved with the visual from a cop. It's not like you are going to find a cop that knows what every single cat looks look on every style of car. Fake it. If your state has emissions probes that are carried around by cops that doesn't prove anything either. It isn't your fault the cat failed. Claim ignorance and say you will get it fixed. Another option is to use a cat made by Dynomax that has 2-2" ins and 2-2" outs with an air tube. This may or may not keep the pulses seperate through the cat but punch it out and send the pipes straight through. If you do it right no one will ever know. Here's the link for that cat. Look halfway down the page.

I can't guarantee that you will pass an emissions test with it but you could sure as hell modify it if you didn't to look like it was working. Just use a single cat with y-pipes at each end if it doesn't work. Either way, when a cop looks under your car, you have a cat.

Has anyone actually had, or even heard, of a cop checking their vehicle for cats? Especially one where it would be a PITA to see them. I'd love to see a cop crawl under my truck and get past the tubular frame, then see past the tranny to the cats mouted directly after the headers.
Honestly, I have never heard of anyone busted by a cop for no cats. Hell, I know LEOs with straight piped Rustangs and Camarslows.
