As for the longevity of cats… As John says, HJS are the gold standard, used by all of the above.

But of course with really really extended track use… I’m taking multiple endurance race style running or bad fuel/tune, you can have issues.

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.

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

  • PistonHeads: 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

Hi there Always a risk joining a forum at a late stage! Apologies. After many years of GT3s, and then odd ball stuff, I have now bought a 981 GT4. Pretty good car! As I find my feet, there looks to be a lot of discussion around headers, throttle bodies etc. Headers/ Manifolds. A lot of respect for the Fabspeed 200 cell cats. Are these easily available? How good are they as a first stage in upgrading? What alternatives are there to Fabspeed? If there are threads, and I’m sure there are, please point me to them! Many thanks Roger

Beware of 200 cell catalysts, even HJS break up far more than OEM

Many thanks Roger Hey Roger, Shoot me an email and I can get you set up. - [email removed] HJS cats are the gold standard, it is a fact that all catalysts can deteriorate, it all depends on driving style and fuel type!

Lots of options for 981 Sports headers with integrated 200cell cat. M&M/FVD Cargraphics Soul And as per the title, Fabspeed. Other styles are available also which relocate the cat to further down the exhaust path. As for the longevity of cats… As John says, HJS are the gold standard, used by all of the above. Usually no issues. But of course with really really extended track use… I’m taking multiple endurance race style running or bad fuel/tune, you can have issues. Just like you would with and OEM cat. These can fail also. There are a few existing 981 GT4 mods threads. I’ll try to find the ones with the most recent contributions.

These can fail also. This ^ HJS metallic substrates are as good as they get, IF they fail, it's normally due to failed O2 sensors and the resultant under/over-fuelling that kills them, or as others have said, a poor tune. Personally I'd stick with the Cargraphic, M & M or FVD products.

POST 7 / ORIGINAL POSTEROriginal post

Hi guys This is good stuff! Have to admit the car is a bit of a gem. Still enthralled by its compact agility, its pace and its comfort. Looks nice, too! So, this is a real keeper, it's great to be back in the Porsche world. Not going to track it, but it will do 15K miles a year at least. I get the impression that the car was genuinely well-received and amazed anyone who drove one. Then as always with anything perceived as "perfect" people had clever ideas! What I am looking to do is simply address the base concerns....intake and throttle body plus manifolds. I'll have a read through the threads suggested and come back with any queries Really appreciate talking with some old names on the forum again......oh and by the way the SVR F Type was fun, but only in a straight line!!
