anyone think that the 'emissions pass protection' stuff they sell will actually work? my honda failed with WELL over twice the legal NOX emissions, everything else seemed fine... did the water decarbonization thing, but since this car has no EGR i have to figure something out... the state gave me a one time only pass, they said next time im sol....have to do it in june

Dunno, you can request a catalog from them that gives a LITTLE more info.
It's basically snake oil.
It is true that a clean engine pollutes less, but the gains of any chemical cleaning would only be marginal compared to what you need.
I don't know about Berryman, but many if not all of the "emissions" kits have a money back guarntee. If you don't pass a smog test they will refund your money. They seem to depend on most cars passing the test and many customers not bothering with the hassle of asking for the refund.

How old are the spark plugs? they might need replacing. How old are the spark plug wires?
O2 sensors can make a big difference too. O2 sensors aren't that expensive and they're fairly simple to replace. How many miles on the engine? it might be time to do a good internal cleaning with ARX or Marvel Mystery Oil or Seafoam.

Twice the allowed NOx really isn't all that bad.
Best idea is to tune up your car (new plugs especially), get a new three-way aftermarket converter (preferably a bolt-on), pass the test (hopefully), and then take the new converter off and stash it in your garage for the next two years. Each time you have to take the test, put it back on.
I did this for over six years with an '83 Civic. That car ran exceptionally lean (and well). NOx is higher in a lean-burning engine, which the CVCC engine was. Couldn't fix the problem even after cleaning out the EGR circuit and replacing the valve, but a new cat solved the problem.
Failing all that, see if you can make your car run richer.

93 1.5l manual with 172K..... plugs are fairly new, bosch platinums... wires are probably old, the contacts inside the rubber look brand new though.... o2 sensor was replaced this time last year with a honda oem one at $300 or some crap... i got a cap thing from the state and they paid for it to pass smog cause im a broke *******, its a $500 limit and the shop used the whole thing to replace an o2 sensor.... not the cheaper one at autozone, the oem honda one...whatever. i can do it again if i want but id rather just handle it myself, its just faster....but i have no clue what it could be, i want to pass.... im thinking a new cat might be a quick-pass-fix but im wondering whats causing the high NOX output... everything else was legal, until they replaced the o2....then the hydrocarbons (i think) went over the limit.
I'd try a new O2 sensor, as this will affect the lean/rich nature of your engine, as it sound like your problems started after this was replaced.
Just buy one online
http://oxygensensors.com/
Should be about $40 or so.
You can also get a universal cat, only like $50 on E-Bay for a high-flow Magnaflow.

Why do people think Seafoam and MMO are better than Chemtool in the crank? LOL. Oh the unbelievers. You can also try a piston soak w/ chemtool as well.
A search for the MSDS of Seafoam gives you Naptha, IPA (is that isopropyl alcohol?) and pale oil. Where as Chemtool is Toluene, Acetone, n-Hexane, and methanol. Nice....

robbobster - it was the same prior to the o2 being replaced, the new o2 only raised the hydrocarbon output numbers, those cats are california legal? the 3-way type?
great prices on these cats, they arent phart-pipes are they? trying to figure out which one will work on my car
undummy - for sure, just wasnt sure if that was what was causing the insane nox numbers while everything else was normal

I wouldn't call it snake oil. I would call it targeted packaging. Berryman (and many other manufacturers, for that matter) package the same chemicals with an extra additive here or there and in a different labled/type of can in order for people to realize they can use the product for a certain application. If the car can't pass emissions b/c something is crudded up, I assure you toluene (active ingredient in Berryman) will work better than most products out there.
Go to www.auto-rx.com and click on "Emissions" read
state test data. Once you understand how Auto-Rx reduces emissions, remeber our guarantee.

I believe the phart-pipes you're referring to are the aftermarket mufflers with the huge tips sticking out the back of (usually) some otherwise underpowered import that now sounds like an angry bumble bee. Those are mufflers or at least, they're supposed to be mufflers even though they seem to do the exact opposite.
The cat is placed after the exhaust manifold/header and before the muffler.
The manufacturer of any aftermarket component can tell you if the equipment is smog legal or not in CA.

Yes, you can get a cat pretty cheap. Same w/ o2 sensors. Many kids w/ loud exhausts don't even have cats if they can get away w/ it.
vairox,
Go to this site:
http://www.car-sound.com/
Car Sound is Magnaflow's parent company. Look up the cat you need, or just call them.
Then go to Ebay and look for the cat using the part number you just got. There are several vendors there who sell them for cheap.
This has nothing to do with the crazy exhaust setups you're referring to.

hmmm the direct fit says its 16 and 5/8" long, one end has an oval "flare spin flange" and the other a triangle shapes " 2" welded flange"
the universale says 13" long and says nothing about the ends... im guessing id have to have someone weld some pipe extentions and new flanges right?

I paid a shop to replace the cat on my saab 900 w/ a highflow magnaflo. All totaled w/ labor it came to just over $100. That was w/ them having to cut the turbo downpipe in two places and rewelding on the new cat.
