catalyst replacement


Ludwig

Recommended Posts

When it's time to replace the OEM catalyst, because it's

been deteriorated too much, what would be the best thing

to buy as a replacement?

Does it make sense to build a 2002 STS catalyst into a

1992 STS because the newer models are achieving lower

emissions&cleaner air??

Or a newer aftermarked catalyst?

Or would the ideal thing be to get the exact catalyst that

was used originally in the car, because it's better

adjusted to the the oxygen sensors, the computer etc.

(still available for my 1992 STS)

I'd get a high-flow cat, and have your old one cut out and the new one welded in. It'll probably cost you $150 total, and like CaddyJack said, will probably come with a lifetime warranty. The converter for an '02 probably won't be any different from a converter for a '92. It might be different from your ORIGINAL converter, but the service replacement for your '92 will likely be the same as one for the '02. Most of the better emissions on the newer vehicles happens before the converter (engine, PCM tuning, etc).

I purchased mine at NAPA it was smaller and looked like a universal cat, but worked fine and stopped the ROCKS IN A CAN sound I was getting in my 91.. I had it welded in at Midas... Mike

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

I haven't actually done it (yet). You can get high-flow converters from places like Advance/Pep Boys for around 100 bucks, or at least you could a few years ago, when I worked part time there. I couldn't imagine installation at Midas would run you more than 50 dollars -- I would hope less.

When the cat needed replacing in my 93 STS, NOT EVEN THE DEALER recommended that I replace it with an OEM - then $600 to $800. I went to an independent muffler shop and bought one for $225 installed and it worked very well until I traded the car at 193k.

I just had a local muffler shop in Houston replace my OEM Cat. with a high-flow aftermarket Cat. for under $ 100, installed.

Thanks Dasher, that is good to know. How did you know you needed a new one? I have this smell in the car when I drive and when I look under the car at idle I can see exhaust coming up from where the manifol meets the front of the cat?

Thanks,

Eric
