GPF part # for USA and ROW
#31
So today my dealer told me that the canisters of my car are empty inside, there's no filter. So is it possible that EU have the monitored one, US have a filter (because California rules?) and Rest of the World get empty canisters?.
My canisters are part No. 982.254.350.N & 982.254.351.N , somebody have looked inside this ones?

according to the C&D article the difference between the the two are that the (in)active filters are not coated with the material that captures the particulate, the active filters are so coated,
and have sensors downstream (of the filter grid) in order to measure the remaining particulate flow

Yes, that might be truth. I have agreed with the head of the workshop to check it out at my next oil change.
Still there's a good chance that the dealer is correct as there are three types, so i'm wondering why Porsche would have a third speccificatio if that one will be the same as the US spec

From what I believe the Q are US spec, P are EU spec, N are South Africa & Latin america. Even might be a fourth spec with the letter L which seems to be for Asian markets (not sure thought) .. so there's a pretty good chance that the dealer is right telling me that my car doesn't have anything inside. Mindblowing because I'm not satisfied with the sound and I was convinced that the OPF was the silver bullet to sound enjoyment...

+1 ... this is also what C&D stated... no active OPF material in the non EU pipes...

Just wanted to do a quick update on this. So I have confirmed that the "N" OPF types also have a filter (south africa / latin america), see pics below.
Thanks to John from @Soul Performance and JC form @JCR-Porsche for their private responses.
I have no official reason as for why Porsche made so many variations of the non-monitores OPF, the only logic thing that I can think of is the convenience of having different codes, so if, in the upcoming years, some markets do a regulation change, would be easier to do all the adjustments having the part numbers already coded differently (specially thinking on the more long term production of the 4.0 GTS).

@metalone Are the GPF cannisters on your car monitored?, when I looked at mine in Canada there was no sensor installed and no hole for it either.

No, they are not monitored (same yours). This filters are as restrictive as cats. So this explains the big power gains on the lower band of rpm that akrapovic publish at their website.

Resurrecting this thread. Here are some pics of the GPF pipes pulled off of my US non carb spec 2021 PDK Spyder.
Note the “T” part number, which is in addition to the suffixes above.
Note the size of the cans...they are huge! They have the full Corning Ceramic matrix.
The shielding makes sense because they self clean like an oven. Unsure how that works in non monitored cars.
Clearly this is a significant impediment to flow and performance.
Has removing these made a difference...lol; oh yeah.
