J Holmes said:Another visual check is to look at the exhaust manifolds. The X51 manifolds merge like the 996 ones for better flow whilst the standard ones are an ugly 3 into 1. Will post a pic if I can find one. On it's own that isn't conclusive as the manifolds are a retrofit for a standard car but if you have the carbon fibre airbox as well then the signs are good. Will also post a pic of the options sticker from my handbook - you can see the X51 code there.
