Looking for some place that sells a reasonably priced replacement cat for my 98 discovery. Any help would be appreciated................

Try your local muffler shop!

Local muffler shop..................... I tried that brutally obvious route, but was hoping for some experienced help so that I could save a little money!!!

Ummm, save money on a Rover. The logic. :laughing:

I would think that your local muffler shop is going to be able to save you huge amounts of cash compared to any Rover application. Hell, they tack on more money on normal everyday things, just because it says "Land Rover". Have you priced a paper air filter at Napa- $17. But most everyone else is under $10 at autozone. Hmmmm.

Not legal in most states on a OBDII rig. They must replace with OEM to be legal. But I just bought 60.00 Catco high flow cats from Summit and welded them in myself. ;)

I talked with Summit earlier this morning and they weren't sure of which part number I needed. Do you remember if you purchased the CTO-6905?? At any rate........... how are they working out?? Thanks for the info.............

A cat is a cat. The smog man does not look at your receipt from the muffler shop to verify that you bought an OEM cat. As long as it has a cat of the right size and flow rate in the same location, its good. And thats out here in the smog capital of the world, Los Angeles. I know smog legal trucks out here running Magnaflow cats and mufflers.

Thanks guys........................... I am all set.......... Summit worked out great............

But the muffler shop can be cited with smog tampering by the BAR if they install non-OEM cats on a ODBII car.

Old Scout,
I agree and that is the response that I got from three of my local muffler shops. I was just looking for a place to buy them and was interested in purchasing from someplace that was recommended by someone and like yourself I will be welding them in myself.......... Thanks again.......

When you say non -OEM you mean like a Catco or something. Unlike a universal fit from Napa or some other shop. I have never seen a cat inspected for OEM verification. How would they even do that? I know San Fran has some crazy laws, does that effect you out in Stockton.

Shows what you know about N cal smog. We have had dyno run smog machines for for five years now , SF just got them last year. :flipoff2:

The cats I pulled out from my rig had LAND ROVER stamped in to there heat shield. The catco have CATCO stamped into there heat shield. I wasn't going to take a chance with getting busted and made sure both cats had a nice thick layer of mud on them when I was inspected.

If the cats are the same size and shape, couldn't you drill the spotwelds and swap heat shields.

That is a crazy law - a new cat would be better for the environment than an old worn out cat, regardless of the make, and surely if it passes emissions that should be enough. How could they justify busting you for having the wrong cat if you pass emissions.

im tellin ya- a 10 dollar handshake and a sixpack for the cholo at the pass or dont pay will make sure the great white hope gets tags this year. :flipoff2:

When you goto your muffler shop just make sure that the cats you have them install meet ODBII standards and you will be fine. I think most states are like this save cali or other emmission nazi states. I just paid $351.50+tax for new pipes, cats, and muffler from the Exhaust Manifolds all the way back at the local muffler shop. Later Nutter

Colorado has the same Dyno Smog machines. I haven't had stock cats on my truck in 4 years, passed 2 smog tests in this time. I find it hard to believe that a muffler shop has to carry or have access to every possible OEM cat on the market just to replace a rusted out defective cat. Here in Colorado Meineke just looked for one that was close in size to the one I had on. The biggest problem is finding one that will fit without hitting the frame.

Nothing but OEM meets OBDII standards, or did you miss that part? The muff shops just won't swap out cats. . It's a 12K fine if there caught! :shaking:

He, he, and I thought Sweden was the world capital of automotive oppression.

We can swap to all-metal racing cats with no problem with inspection. A guy in the area did that to a Viper and he is all smiles. That is what I will do with the 4.6 if the stock ones go.

So what happens to YOU when you tell the smog inspector. Oh, I welded them in there myself.

Eric not even in CA, he's in Ct. Are they this ridiculous there too?

Update - just found out that here in Ct. the muffler shops are allowed to install universal and/or direct fit aftermarket cats. Whatever the case I have finally settled on a stainless Y pipe with cats.............. so much for saving a buck!!! Welding in universals cats looks like a pain in butt. The OME cats are offset from inlet to outlet while the universal cats that I looked at today are straight from inlet to outlet. Also none of the universal cats that I enquired about today are 100% stainless whereas the Y pipe ocnfig is completely stainless.......... Once again, thanks for the interesting input.........

Sorry to be late to the game, but if you take it to the dealer they will replace it for free. The .gov warranties all cats (on new cars at least) for 8 years, and will replace any failures at their cost. Mine failed 3 months before my 8 years were up, and the dealer replaced them at no cost to me. They were the ones that informed me of this deal/law.

Hmmm, Interesting.

>> I find it hard to believe that a muffler shop has to carry or have access to every possible OEM cat on the market just to replace a rusted out defective cat.

that's exactly right - and just about none of the exhaust shops in seattle will even touch a land-rover because of it. even though my older rig isn't obdII, the shop i did find willing to weld in the catco's for me had some hesitation, and none of the national chains would touch it with a ten-foot pole; said they didn't work on them period - aftermarket cats nor could they supply a generic replacement of some kind. the whole deal with emissions is a real pita.

Why would I even bring it up? :shaking:

You can replace cats all day long, they do not have to be stock by any means.

Fed warranty is 8 years or 80,000 miles................. I have 118,000 on the clock......

ok- for arguments sake, let's say i want my truck to pass smog this year in CA... anybody done it the CB way? now im kinda motivated and the Cholo's sixer is lookin pretty good.

I'd like to see a regulatory citation that states this is the case. Sounds like an issue of federalism at its finest, along with some restraint of interstate trade.

Where's Fij when you need his legal expertise :flipoff2:

I have about 6 months before my CA smog. Running Dynatech high flow all stainless cats in 3 inch pipes all the way back from the stock mainfold, with a chipped 5.0 liter in place of the 3.9. It's going to be interesting. I'm thinking that handshake is going to need a Jackson, forget the Hamilton. ;)

doug- i'll keep you posted on what i find. im gonna try the "legit" way of "cheap bastard" way of gettin smog legal in CA.

byw, you get a load of the Great White Hope since i got the tires n trim on there?

I'm still waiting for my regulatory cite!

I have yet to see a federal environmental regulation that is based on something other than a performance standard, versus such a narrow engineering standard.

C'mon guys, you all were talking so confidently, let's have that regulation, chapter and verse!

Well, let's see:

I'm not Ron, although
I am a lawyer
I only did a quick search
I did see consistency in what I found


40 CFR 85.2122 starts a section on what parts can be certified as emission-critical parts. Listed in there under (15) is "oxidizing catalytic converter," which DOES list parameters of "conversion efficiency," "light-off time," and "mechanical and thermal integrity." Nowhere in this section is "OEM" or "Factory installed part" -- which makes me think that doesn't matter as long as the part meets the performance parameters of the administrative code.

I'll keep looking and see what else I can find.

EDIT: That's all for now -- my eyes are glazing over from reading that stupid administrative code. Also, the above is not legal advice, etc., etc. (unless you pay me) :flipoff2:

1: I'm not a lawyer, but used to play one at work (the only school that would have me, I couldn't afford to attend)
2: I used to be an environmental engineer
3: What you have stated is consistent with what I expected to have found-a reference to a standard of catalytic oxidation efficiency, rather than a proscription to use a specific compound or orientation.

Most CAA regulations merely state that a given percentage of the pollutants must be removed using generally accepted technology. I've only been out of it for a year and already, I can't remember what the term was for what was coming down the pike!

Curiously, the CAA is the only federal environmental regulation that directly impacts private individuals (the CWA has been interpreted to include private individuals, but that was the result of the judiciary, not the senate, nor the administrative agency)

Where does the GWH live here in L.A.? I know I know you, BM -- but can't put a face with the handle....

More clues...?

DW

our relationship is based on a single 285/75 BFG MT. hows that for a clue?

BM, gotcha now! I don't think I've seen GWH in a while. Post a pix?
