Very nice, and it looks like the Scorpion Exhaust, have a look on the top of the tailpipes and bottom of the silencer as it should be etched with their logo...
The Scorpion is a good move, great upgrade over the OEM system, comes with a new Midpipe, Rear Silencer and fitting clamp, if you need anymore info please do let me know...
The Sat Nav was an optional extra on all models/years…
The early 350z, from 2003 through to early 2006 had the Sat Nav hidden under the cubby lid, and the Mark 2 350z, from about Mid 2006 had the screen permanently on display…
