I am looking to replace all 4 cats on my 1989 CV 5.0 I have seen the Catco on Ebay for sale.Are the universal fit both the upper and lower cats?If not does anyone have any part numbers for either one?I am looking for the stock fit,I believe it is 2" correct me if I'm wrong.
Thanks

no they are not the upper and lowers. Save yourself some money and just go with 2 cats. Now would be a good time to put on headers. I got shorties and fab'd downpipes with 02 bungs and used catcos. Or you could put cheapo mustang shorties and get a catted h pipe from summit and fab that on. Just some ideas. If your gonna do the exhaust, might as well improve it...

With only 2 cats would there be a problem with passing emissions?

I passed with flying colors. Even with my H.O. and advanced timing.

Aftermarket replacements are a single cat. They combine the two stages into a single unit.

You should have zero problems with aftermarket singles. My has truck got universal Walker cats (one per side) (they are only have about a 12" body length) and they got my emmisions equipment lacking truck to pass its e-test with flying colors (as in, it burned cleaner than my Grand Marquis on everything but NOx). These walkers where about 5 years old at the time. They are still on the truck.

My catcos are 2 years old and have been on both of my vics and still work beautiful. How much are the walkers?

I think the cats are 2 1/4" each, at least that's what they were on my '92.

I may go with the catted H-pipe from Summit racing.Does that already have the bungs for the upper O2's? I think I may stick with the stock headers for now and I will go with Dynomax Ultra Flows.I have them on my 99 and I like them alot.I am also going to put 2.25" pipe from the muffler back without resonators.

I'm not trying to be an @$$ b/c I don't have a box, but are you sure that the cat pipe isn't 2 1/4"? I know on mine the cat pipe was 2 1/4" (where it wasn't crush bent to beat all hell) and the rest was 2".

If you get an h-pipe from summit, you're gonna have to get at least stock mustang headers, because the flanges are too big on the h pipe to fit on your manifolds. anyways, the hardest part is done if you buy a mustang h-pipe (o2 bungs). Right now (if you don't know) your o2's are in the manifolds, so not only would it be logical to get headers, but it is cheap. Get stock mustang headers from ebay.

You may be right, 289. I never measured a cat. I know the exhaust is 2" tho.

well if u need to pass emissions try this out i dont know how this might work or not it would be great if it did though put ur cats higher up on the exhaust pipes to get hotter quicker because the cats only work after they get to a certain temp this is what i heard they might clean a little better if they are hotter but dont quote me on this i do not know if this will work
