I didn't do it personally, But I want to. Frosty, I think this is what you speed shop was talking about. Not too shabby. I got the pic from another forum. It compliments the color of the roofrack and rims well.
I was considering doing the same thing on the RAM air intake you drew up, the problem I run into is that the radiator will not allow the piping to come across. Have you accounted for that or figured it out?
You can make your own grill like I did with the Aluminum grill sheets from APC. I cut and fitted the red grill to the bumper, replacing the stock plastic. Looks good on my Abyss GT.
