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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi my Catalytic converter is failing and I�ve been trying to get it fixed since January. the Porsche Indy I use (Chicago) has not been able to source an aftermarket CC- about $1k, when available. The Porsche factory replacement is about $2.2k! is anyone else in this predicament? sucks- I definitely can�t drive, track in this condition. would u trust a used one on eBay etc? Thanks so much

JUst installed magna flows on mine. check them out.

I have two used OEM sets of cats. 35K miles on one set, 107K miles on the other. PM me if you're interested in either.

POST 6Original post

The good news in Illinois is that they don�t sniff test. So you are able to take a look at aftermarket. I�ve read that aftermarket 200-cel cats perform well and sound good, aren�t too expensive.

hi, thanks so much I heard that it�s risky to trust a used converter. but, looking at these threads, it sounds like replacing with a used device is somewhat common and not particularly risky? im not a mechanic- I do my brakes and oil and that�s about it! So, sorry if I�m asking silly questions. again, thanks everyone tony

POST 8Original post

I had a cat come apart internally and was able to buy one from a rennlister with sensors for a fair price.That was three or four years ago still works good. I paid under $350 shipped for used one. The seller had complete performance exhaust installed on his car and the stock cats worked fine,still are.
