anyone have photos compairing the underbody of track edition vs non trackedition?

Anyone have a picture of this underbody diffuser the track edition supposely have?

 

they have these little black boxes in teh rear right on box sides the stock muffler! Im a buy those soon just to slap in! hehehe. there 80 bucks

 

The track model, as mentioned, has small covers in the rear of the wheel wells and there is a small diffuser at the front of the bumper. Its about an inch tall and it runs almost the whole length of the front bumper. I don't have the track, but I have the aero package and I took the front diffuser off because it kept hitting things and getting torn up. Also as mentioned the rear wheel well covers can be purchased. Other than that the bottom of the track model is the same as all the other models.

 

What purpose do the rear wheel well covers serve?

 

Check Courtesy Nissan for photos of the aero package.
