You do realize you are responding to a four year old post expecting a reply?

That's ok, I'm still around.

So They didn't actually get a Porsche OEM, but something they replace the OEMs with. In the meanwhile I shattered that one, it was pretty weak. The high frlow cats the guys from Ultimate Racing are using in their DPs and TPs work fine for me. They are magnaflow 59959. However I noticed that the exhaust smell becomes more and more noticeable with time with these cats, so now I'm going to buy an EURO6 cat which will cost me about $900. From my knowledge I still have the record for the most powerful and quickest 2.3DISI-T powered car fully emissions compliant and I intend to keep it, so for me it worth the money. Otherwise the Magnaflows will be just fine.
