There are some bungs in the set I have but they come with plugs and don't get used.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

12 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • 986Forum: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Found out from my indie that the cat converters are clogged up, left one almost completely and the right close to it. So what are my options? Pollution is not that big of a deal where I live, no emission testing. So do I replace or cut out, add new exhaust system? What has anyone else with this issue? I just had all four O2 sensors, MAF and plugs replaced.

POST 2Original post

Try these guys for cheap headers and test pipes. Top Speed Auto Accessories, Inc. ....or put used cats on the car. Either ebay or try forum member itsnotnova.

POST 5Original post

I have a complete exhaust from a low mileage 2001 S if you original parts

POST 6Original post

Just 'gut' the old ,plugged cats to ensure that this is the problem. But you will be plagued with Trouble Codes / CEL. Then you can get a good used pair?

POST 7 / ORIGINAL POSTEROriginal post

Does the Top Speed cat test pipes spit out codes/CEL?

POST 8Original post

No, there are no sensors in the secondary cats that these pipes replace. There are some bungs in the set I have but they come with plugs and don't get used. You can gut the old ones as suggested that may be able to be done right thru the opening with the cat on the car.

POST 9 / ORIGINAL POSTEROriginal post

I'm sorry, I should have said it's a 1998 which I think it has only one set of cats.

POST 10Original post

Yes the 98's only have one set of cat. Pretty certain that you will need to replace them to avoid throwing codes.

POST 11Original post

If the check engine light being on all the time bothers you then either buy some used cats, or gut the ones you have and get the electronic downstream O2 sensor simulators that fool the somputer by sending the proper signal for perfectly functioning cats. ~$65 each and plugs into the downstream sensor harness. The cat matrix is ceramic so get out the hammer and a metal rod through the upstream O2 sensor hole and hammer away. Or weld an aftermarket new cat in place (~$185 + welding) Or get some sport cats $$$$ Lots of options.

POST 12 / ORIGINAL POSTEROriginal post

Thanks for all the suggestions!
