maybe your car isnt quite running right? I have one
on my car for a year now, it passed NYS inspection
and performance is the same as the RB pre silencer I took off, which made the car fail emissions, the exaust is cleaner and doesnt make my eyes tear when standing behind the car.

Second that, I've had no problem with mine. If yours burnt out your are probably running lean.

Catco is OEM on a lot of cars.

i was going to chime in and say they probably stink and likely glow, but i didnt want to speak too soon..

especially when, to my amazement, i looked at the cats i just chopped off my car, and my main cat is a 'Catco'

car passed an e-test, and i was suspicious of the cats being clogged, so i had them chopped off..

my precat which looked burned up was already gutted, and my main cat was still looking good - not clogged

SO! heres my review of a Catco catalytic converter for an FC.

------------------------------

- i am unaware of when the cat was put on the car, but it looks pretty old.

- the precat was GUTTED, so the Catco was doing ALL the work

-passed an e-test with flying colours.

- it stood up to lots of burnt oil during a decarboning process using MMO from the previous owner

- it stood up to the rich running and sometimes smoking car when my car was running to rich due to weak spark

- it stood up to (what i found out to be) possibly an oil control ring going out? my car burns extra oil at high rpm only if i hold it up high for longer than 30 seconds. (which i never do, but DID do a few times during another testing phase)

- after all this, when i removed the cat a few weeks ago, it was still clean on the inside, and definately NOT clogged.. keep in mind the cat has (visually) been on the car for a noteable amount of time, and was still clean as a whistle when i removed it.

so, i didnt think id be doing a review, until i stumbled upon the fact that my main cat WAS a Catco cat.

but, considering, i will give it this:

'Catco' Brand Catalytic Coverters -

as reviewed by yours truely.

Thank you everyone, im having smog troubles, and its the cheapest cat i can find. What kinda numbers were you getting on the E-tests, and does your state use rollers?

Here is a site I used when my 87 base was failing emissions... HAILERS gave it to me. Last I checked, a bolt in replacement cat for the S4 FC was 179.00.

NYS inspection has rollers.
I ran H.C CO NOx
.49 2.5 0.26

NYS limits: 0.80 15.0 2.00

this was after the car sat since October, I just had it
inspected last week, think I could have done better
with fresh plugs and after a good drive, but there you have it.

2.5 co wont pass in CA, i think im gonna go for the duel converter system j-rat posted, which looks the be the samce catco system on summit.

I bought my cat here:

The catco converter works fine on my car.
It's MUCH lighter than the stock set-up and the fact that it flows better will be OBVIOUS to anybody who looks into both of them.
Summit has both the single main cat and a dual cat pipe that'll replace all three cats on an NA car. I think I'd probably buy the dual cat pipe if I was to do it over again. Currently I have the stock pre-cats cleaned out and the Catco main cat.

One caviot, the Air pipe is a tad long on the Catco. It's no big deal on my car but it could be a problem in other applications.

Best selling point - price- if it burns out in two years, so what? buy another one and you've got 4 years of service for less than the Bonez set-up.

You could probably search for my name and cats to find the photos I posted when I did mine in March.

Cwaters

ok, I did the search. call me board at work.
