Sorry....can't help you out with the picture of the factory tips since my car won't be her for another month or so but look around on the forum for muffler delete.
The aftermarket tips form the SLP LMI or Magnaflow Comp axle-back definately look better than factory but it's just a matter of how much money you want to spend. Right now I plan to go as cheap as I can for a little while because my long term plan is to install Long Tube headers and full 3" exhaust.
Here is the original muffler delet thread. This doesn't have the #11386 though but you can get an idea.
