Factory shocks are twin-tube, according to any specs I've seen from Porsche. ( Example from: http://press.porsche.com/archive/products/press_kits/press_kits_2001/PDF/24-29_RELEASE.pdf )

"dual-tube gas-charged shock absorbers provide flat cornering." (emphasis added)

Bilstein aftermarket products should be easy to find out whether they are twin-tube or monotube. (They may offer more than one option).

Actually, I just looked up some specs on bilsteinus's site and it does see that most aftermarket Bilstein options are indeed twin-tube (not mono tube as I initially would have guessed).
Bilstein, Innovation and High Quality Since 1873
Lists three shock replacement options (B4 OE equivalent, B6 HD, and B8 Sport) all indicated as "twin tube strut assembly".

So I guess I stand corrected and actually the aftermarket Bilstein struts for this application are actually twin tubes, just like OE shocks.
