Dane:

I think that there will be NO particulate filter in the RS. First they will supply the EU market, after that ROW.
A particulate filter will come with the next generation (GT4, ...).

It would be "stupid" from Porsche to deliver the GT3 without an the RS with the filter.
There is no way that the filter doesn't "influence" in a negative manner (Sound, performance, ....).
 

But it would be as dumb to not fit a particle filter and so to limit production to a few month when they could of made many more over a 12 month period ....

Maybe that' s what they are debating now ? At the same time it is hard to believe nothing as important  is already set now, so close to launch time .
