I recently picked up a Carbon Fiber styled Rear Bumper Diffuser for my '09 Box and the fitment is great.
I used some Insulation Foam on the ends of the diffuser to fill/hide the gaps. Easy and nice looking mod.
There are also plain black diffusers of the same style as well.

 

Beautiful DIY Mod, CiRiS!



*Notice: his Nice, Rare SL Sticker on his Bumper Corner.

They are in Limited Supply. Once they are Gone, They are Gone!
