However, it turned out to be a bad cat, which was replaced by Porsche.
Leading evidence: 'cat' (1 discussions report identifying this cause; no attributable repair resolution).

The real issue is the durability of the honeycomb like filter that is used.

It was the rattle that got my attention both times.

And the one nice thing is that they replaced BOTH of them. Additionally, I am also pleased that my dealer, Pacific Porsche was helpful in getting this resolved.
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.

As you may recall, my cats were diagnosed to have cracks at 80,909 miles. Well, these were the third set of catalytic converters on my car since the car was new. The first replacements in 2005, and another in 2006.
Since my car was out of the Federal Emissions warranty by 900 miles (8yr/80k), and so the dealer said it'd be $1600 for the catalytic converter (single). I told the service manager at the dealership that I'll contact PCNA.
I did so and initially they rejected my claim for goodwill repair because they notedd my mileage incorrectly at 89K miles. After correction, I'm pleased to say that PCNA came through and covered the catalytic converters. And the one nice thing is that they replaced BOTH of them.
Additionally, I am also pleased that my dealer, Pacific Porsche was helpful in getting this resolved. In my past car ownership days with Audi, it was futile to call up Audi of America expecting any help in any matter. So, I went in with skepticism, and was proved wrong.
Pacific has really always taken care of me. This dealership is over an hour away from where I live. I have several Porsche dealerships near me, with the nearest being 10 minutes away, but I choose to go to them, as I find them reliable and no-nonsense.
I'm hoping these set of catalytic converters last a little longer than 2 years.
Good for you, sounds like you go through cats as much as my car does (02). I will be starting my forth set shortly but I'm still under warranty until summer of 2010.
I blew a cat a couple of years ago.... er..... wait...... let me rephrase that.
A couple of years ago my 996 had developed a rattle that sounded like it could be from the mufflers. However, it turned out to be a bad cat, which was replaced by Porsche. Some dealers won't replace it under warranty until the cat is bad enough to throw a CEL, while others will do so if they can determine that the cat is bad without the CEL. A lot of it depends on the dealership.
just to let anyone know, i have a set of stock cats from my previous MY 01 996, car had 15k miles when i removed them. If anyone needs a set let me know and we can work out a great deal.
Thanks jumper, Tim and russo.
Despite some truly epic potholes here in MN, I think mine are OK. My rattles occur with bumps only. [not counting interior squeeks, etc., that are best handled with a Stevie Ray Vaughn CD)
i'm wondering if Porsche's premature failure is due to excessive vibrations and cat design. I've never really heard of these things needing that much replacement in other cars, especially ones that don't ever see snow and rarely even rain.
heat from engine? sounds silly, but who knows.
Is there any danger of not replacing your cats when they start to rattle? I've heard mine a couple times at start-up, but I haven't thought anything of it...
and have to be to withstand the heat and forces they're exposed to for 80,000+ miles without failing.
The noise might be from some other source.
I would not replace the converters unless engine performance affected by blockage or reduce flow of exhaust gases or unless a warning light and error codes and with proper follow up diagnosis determines the converters are at fault.
Sincerely,
Macster.
My left cat has the same issue... have had it for almost a year now. Last time I went to hendrick porsche here in CLT, they told me that I probably will have to replace the cat and they quoted me a price. Nothing mentioned re replacement under warranty... car has 45K miles and is from 2003... also still has a month of CPO left.
Any advice?
Dutchie, I would wait until it throws a CEL, then take it in. Even if you car is out of CPO, they are required by federal law to replace any "emissions" related issues for the first 8 years/80,000 miles.
Here is a link to the warranty overview. At the bottom of the page is a PDF file for the 2008 Warranty. See pages 1, and 17-18 for the emissions warranty.
Warranty
My '03 has had 1 left and 1 right replaced in the last 20K miles. Dealer did both w/o charge under CPO. Never threw a CEL. It was the rattle that got my attention both times.
So what number did you call, 1800-porsche? Any advise on making this call? I am having the same issue, and i'm just 2 months outside of the 8 year period, hoping they will help me out of goodwill, for a 1st time porsche owner, and it's a cpo.
Thanks,
Paul
Great story, great results.
A solid and more interesting alternative to stock cats are the Fabspeed "U" pipe 200 cell sport cats. They're beautifully designed, look great tucked underneath, and so far work as they should *no drama*.
I am having my 4th set installed in the next couple weeks. I've had 1 cat rattling for a year now, with the check engine light. My other cat started throwning an error last fall so I waited. Car goes off the 8 year warranty in the summer.
Going to pull them off as soon as they go on, and put the fabspeeds on. I know the OEM's won't last on my car, so I am better off getting the new ones installed and taking them off and storing them in case I need them if I sell the car in the future. There is no way I am paying $1600 per cat when the fabspeeds are priced less for both.
I just hope they are better made then the OEM are.
not sure
this is what I am thinking of replacing them with
996 Sport Catalytic Converter X-Pipe $1,495
* Fits all 996 Vehicles 1998-2005
* 340HP/308 ft-lbs of torque to the crank.
* 996 Sports racing catalytic converters give a HORSEPOWER and TORQUE gain to all 996 cars. High Quality T304 SS C.N.C. mandrel bent tubing for maximum exhaust flow.
* High Flow imported sports racing catalytic converters for less restriction and more power and more sports car sound. Fits all cars worldwide. Porsche factory warranty
* Simple bolt-on direct replacement sports cats for the factory OEM Porsche catalytic converters.

reason why I ask is FVD sell similar and is trimetal.... its supposed to last a long time with high temp application.... Im thinking of going with this instead of fabspeed... though I have not seen any reviews on. I am a fan of FVD, a bit expensive but all made from the motherland.

Red,
IMHO
Go with the FVD. Put them side by side w/ FS and you will instantly know that the extra money was well worth it. I can already tell by the pic that the FVD quality and materials, fit and finish are significantly better.
I just put Cargraphic cat bypass pipes on the Cayenne. The quality, fit, and finish was hands down better than FS.
If anyone wants to see some beautiful welding, got to the RSS site and check out the welds on their X-pipe, Awesome!
Good news, after PNA told me they're not going to cover the cost of my "internally broken" driver's side catalytic converter, they emailed the dealer saying they WILL COVER the cost instead. Just picked up my car and the ck engine light is gone, a new cat behind the bumper, RMS and IMS leak fixed under CPO, and 15k service done w/ complimentary alignment. They also cleared my fuel tank vent line because I was complaining about gas pump keeps stopping even when it's not even close to full. I'm very happy to get back into my 911, even the loaner was an almost new Cayman S PDK!
