Isn't the factory grill vertical slats on the FR? I know there is an additional honeycomb piece you can get seperately and then attach behind the slats. is this what's on yours? If so then yes the honeycomb behind can be removed easily by taking the grill itself out and then undoing the clips for the the honeycomb part. To take the grill unit itself off, lever the two stop plugs on top and then get a long flat head screw driver to poke down the cap to get the clips at '10 to 2'. I just replaced my grill today this way. I've got an aftermarket black grill so there's no chrome on my car now, mesh came seperate on a sheet which i've now cut to size and stuck to the surround.
