Hey Guys, can you give me answer to this question?
I got now a Greddy Spectrum Elite Dual for my s2k. And we in Germany need a certificate for this to drive legal. So i have contact Greddy and they told me, that the owner of this exhaust in the USA has to go to a test-center and then you get a certificat for your prossesion.
Is it possible that one of you send my the certificat per email?

Your Ramon
