I just bought the Magnaflow 94006 cat. The guy who sold it told me that it is suitable for the FZJ80 (mine is a '96 LX450) but on this forum there's almost no mention of this cat model.

There are no emission tests here so I am not fussy. I just want to get rid of the 'insufficient cayalytic flow' error code. Will this cat do it?

Oh, and do I need two of them or only one. I've also read somewhere that people install one cat instead of the OEM two. So how many do I need actually?

Why not simply replace your rear O2 sensor with a dummy one, and run without cats at all?

Seriously?

I'm giving Al Gore you home number.
 
Al's runnin' straight pipes on his Prius.:clap: I'll bet he runs his A/C with the windows down, too.

Those are fighting words!!:flipoff2:
 
Yes, the 94006 is 50 State legit for your year model. This should be a weld-in, single inlet-outlet, 2.5" diameter. It's up to you if you want to abort the secondary cat, don't know if this would trigger Check Engine light or not???

Great! Then Al Gore can fly out on his private jet, and we can fight Global Cooling together! :lol:


And yes, seriously. Even sans cats the '80 will be much cleaner than many other vehicles (including the ever mentioned Prius, if you include the environmental "cost" of manufacturing).

But lets not turn this into a flame war. ;)

It would only trigger a CEL if the computer thought that the air flow out of the cat was out of spec. Some people have gotten away with running one, with no CEL's or only periodic CEL's.

I had no intention of doing so. However, my position has always been to retain any pollution control devices where-ever possiable. If Everyone that lived in non-inspection states ditched their cats can you imagine how bad it could get in some places? Uck.

I live in a state where I could easily get away with loosing my cats- not even a visual inspection here- but they're still there.

I will admit to toying with the idea of ditching my PAIR valve set up though...

I have no plans on ditching my cats (in fact, I'm planning on retaining them when I have my exhaust redone, despite the added cost that keeping them will cause). That being said, if they plugged up or somehow else otherwise became inoperative, I would not plan on replacing them. Factory costs are $$$, and aftermarkets are still pretty spendy.

I've talked with several people who have removed their cats (or hollowed them out) and still passed the sniffer. It's likely that the 80's would pass the sniffer as well, meaning they're well within the required limits. (Assuming decent maintenance.)

I'm all for taking care of the environment and being smart about things. I personally believe that global warming is extremely questionable at best. There are some very strong scientific papers out there showing evidence for global cooling. (Michael Crichton has an excellent book examining this, State of Fear.)

In certain circumstances ditching smog equipment makes sense (and I think that our government is far too restrictive on it).

Just my two peso's, and apologies for hijacking the thread. You can now return to your regularly scheduled programming. :p


(Oh, and while I don't have to worry about PAIR, from what I've read removing it makes a lot of sense. If I had an 80 with PAIR on it, I would probably remove it at some point myself.)
 
First of all, removin the cats in this specific vehicle is not a good solution. An O2 sensor simulator is not good either.

The truck's ECU uses signal from the second sensor to adjust long term fuel trim and this has impact on mileage and engine performance (probably an overall too rich or lean condition).

Second thing... Don't make me laugh. One Magnaflow cat cost $50 plus shipping. So who's talking about big money?

I have a pair of those cats and I am simply having a dilemma. Install both or install one and sell the other one to a friend. Currently I am leaning towards installing two cats but if I get evidence that one will be enough not to throw a code, I will stick with one.

Currently I have a straight pipe in the exhaust. The PO got rid ot the cats.
