I removed mine and went for the de-badged look when I had my 350 which looks pretty good imo. Pictures are somewhere in my old build thread which is in my signature.
When I took off my old "350Z" badge I actually damaged the "Z", ...another member kindly sent me their old one as I was thinking of refitting it. If you don't fancy the de-badged look then I could have a look to see if I still have the badge he sent me.
It might take me a day to find it though as it's in a box in the garage somewhere & we've just moved into a new house. I'll let you know if I find it (or not), ...no promises.
