I'm soon going to post photos and a review of my good friend's Cayman S project recently completed. He just completed a transplant of new from Porsche X-51 997 3.8 with custom, headers, exhaust, PSS9. Dyno/ECU tuning in the next week or so. The car is an absolute monster and the sound...unbelieveable. The PSS9's transformed the handling of an already great setup to something so many levels more it's truly hard to beleive. Too bad the factory will never allow this setup. http://www.mindovermotorsports.com/
