SELECTING THE PROPER UNIVERSAL:
(Non OBD-II Vehicles)

Engine Size
Determine engine size before selecting the converter. Converters are listed according to legal engine size.
If engine has been changed and is not the same model year as the chassis, proceed as follows:

1. If the engine is older than the chassis, select the converter according to the chassis model year.
2. If the engine is newer than the chassis, select the converter according to the engine requirement.
3. Inform the owner that improper engine switching is not legal. The customer and the shop that switched the engine could be fined $2,500.00.

Converter Type
Determine the type of converter being replaced. Check whether the converter is a 2-Way, 3-Way, or 3-Way + Air (See EFCI Click Here).

Vehicle Weight (Test Weight)
Determine the weight limit before selecting the converter. Converter coverage is listed according to Test Weight.

How To Calculate Vehicle Test Weight:
For passenger cars and light duty trucks less than 6000 lbs. GVW
Gross Vehicle Weight (GVW) Less Vehicle Capacity Plus 300 Lbs. = Vehicle Test Weight.

For trucks over 6000 pounds GVW
(Gross Vehicle Weight + Curb Weight) x 1/2 = Vehicle Test Weight

This information can be found on a tag inside vehicle door or in the vehicle owner’s manual (Use as estimate only).

Yes. If your car requires air, and you dont have the airtube then you are in trouble. Otherwise it doesnt matter. Thats why its capped off from the factory. It doesnt matter.

Sigh ....please READ the previously posted info. There are 3 different types of catalytic converters. They have 3 different applications. For a replacement catalytic converter to be legal, it has to meet the requirements of the vehicle it is installed on. Catalytic converters are not a "once type" or "once size" fits all.

READ the government regulations first, before making such a silly statement...

We are talking about the function not the law. Not once has anyone but you talked about the law.

Functionally they are the same thing. That is why they have a cap on the air tube. There is no explanation besides that. If we were trying to keep stuff out of the cat then we would have a huge cap on both ends too.

I did......then I called my brother, John, who is an ASE cert'd mechanic, working for Craven Tire in N. VA.....the Dulles Airport location, actually (Sterling, VA to be precise.) He's also a state cert'd emissions and safety inspector and mechanic.

Asked him last night if a 3-way cat with air tube can be used in place of a non-air tube equipped car. Said it could without problem.....both cats in question are 3-way cats, just one has the air port for additional oxidation.

Said in cases where the air tube is present but the car doesn't have that system, the air tube is capped off and left. The rest of the cat continues to function just as any other 3-way cat would. The oxidation circuit is essentially disabled by the tube being capped.....but that doesn't hinder the function of the cat whatsoever.

Now, it's illegal to cap the air tube if the car is supposed to have the oxidation circuit intact. But you can use a 3-way cat with the oxidation tube capped in a car that needs a 3-way cat but has no oxidation circuit without problem. Says if the cat functions properly, it passes, capped air tube or not....depending on if the car is supposed to have the air tube functional or not.

Ondonti:
Well the LAW is the whole reason there is even a cat on the car, no? Would you put one on if you weren't legally required to do so? Didn't think so. And functionality is STILL effected if the incorrect one is installed.

Spiritedwoman:
With all due respect, the Pennsylvania State police (who oversee State inspection/emissions regs here) as well as the EPA will prove your brother wrong.
That's not to say that some State inspections mechanics won't let it slide...but if they get caught, it's a hefty fine. I spoke with quite a few folks before selecting the cat on my car...and I was told SPECIFICALLY (by the State Police INSPECTOR, no less) that the EPA regs, must be adhered to, or the vehicle will be failed for Emissions. Argue all you want, but the facts are the facts.

Personally, I don't really care what cat anyone runs....I was just trying to help the initial poster from getting into any hassles with emissions testing...

I don't know about Harrisburg, but up here in Lehigh county, as long as the car has a cat, it passes. There is NOTHING in the inspector's manual about the proper cat or testing the cat, if it has something that looks like a cat and that wasn't obviously tampered with, it passes. I've never heard of keeping records of cat replacements or anything like what you posted before. My family has been operating a garage for more than six years now, and we've been doing emissions since they were requiered. I have an emissions license. You can also quote PA law all you want, it won't help irocelectric93 since he's in a completely different state. Ondonti and SpiritedWoman are completely right, a capped off air injection tube does not affect cat performance at all.

[jmitch]

lol try a capped cat in cali! your car will fail ,but he's not in cali so your safe.
if it will work for you use it. i can see were every ones coming from 440trk from the perspective that if its not exact you will fail in areas were they are emissions sticklers. and everyone else because it will work and most other places where emissions tech are as strict as in cali.

So you don't consider a complete NEW cat AND exhaust to be "tampered with"?!?!?

Well thats funny....because those were the EPA FEDERAL regulations. You know...the ones that Pennsylvania has to legally abide by, if we are to get any Federal Funding for our highways. (and Pa. most certainly DOES get Federal Funding)

If your family shop has not been keeping track of Catalytic coverter replacement info as necessary, I suggest you look into fixing that ASAP. There is a form with every new Cat you install, that is to be filled out and recorded.

Most of what I quoted, were the EPA regs , and they are not just Pa, they are FEDERAL. So yes, it DOES effect irocelectric93.

Then please school me on why Cats are rated for engine size, vehicle weight, Converter type, and/or make, model, and year for application.

Look...I'm not trying to be an Arse here....just that if anyone is going to put a new CAT on their vehicle, why not just use the CORRECT one to begin with. Using anything else is just asking for trouble.

Some mechanics may let it slide if it's obviously been under the car for a while...but you can STILL get nailed by a DOT inspector if they're in the shop for any reason.

Like I said, you guys can do what ya want...just don't say you weren't warned.

[jmitch]

you got that exhaust on there yet? curious on how it sounds

[jmitch]

you ever get this installed?

[irocelectric93]

Oh how i wish. The car was being worked on for a short while before i started going to Ranken. The interior is nearly all gutted so i can line the hatch floor with dynamat. Leaving the back seat out this time. Took off the spoiler etc and fixing a few cracks and breaks in the plastic panels on the inside. The exhaust will probably go on as soon as i get the money to buy new stuts so i can put on my eibachs. Once i get the car lowered and settled then i can see how much room i have left for exhaust. Hopefully when the weather gets a bit over 20 degrees ill get it done....although im tired of welding....i weld EVERYDAY at school....blah the exhaust will be on soon though. Ill get it on before it goes for paint or probably before i even start prepping for paint.

[mopar3.0]

on a side note my aero stealth suv muffler just came , its big,, over 28 inches long,6 high and 12 wide, single 3'' center inlet and dual 2.5. planning on having the muffler at the rear of the car with no tips, gona have to loose the spare tire whell thought

[irocelectric93]

so i thought id throw up some pics. Welded part of the exhaust for the car today....which was a semi failed attempt. Welding without argon sucks...im sure brent can go with me on that. I weld everyday at school but i get home and without gas im pretty much useless ive realized. Not that MIG welding is hard anyway though. So you wanna see some crappy welds...there you go. Oh it didnt help that Lincoln welders are retarded and instead of voltage numbers they have letters....A, B, C, and D....uhhh what? first bead was on A....ha that was funny. then i realized that my grinder is broke....sucks so there we go. Also the interior panel broke when i was taking it out so i have to fix that....blah. Thought id put the fidanza in there for laughs too.
<P>

[irocelectric93]

Oh and it didnt help that my helmet....blows at the moment. I think i need to put new batteries in my lens...its not dimming right so i cant see my weld puddle at all.
