lower grills aluminum/titanium? HELP please :)

[AlpineMsix]

Okay so im on a hunt to do this mod. I want the lower grills of my 4.8 to match the front grill on my hood. I have been wanting to do this for a while and was to scared to simply go into a paint shop becasue it might not come out right.

But now from an earlier thread i found out this can actually be done. So im assking, please if anyone knows about this option at all, can you guys provide me with a part number or a color code(of the front grill) so i can maybe either replace the lower grills if they already come aluminum/titanium, or simply get them painted by using that "color code"


Here is the best pic i could find, I know this picture could be somewhat photoshopped, but It kind of explains what i want.
