Need help finding a picture and info on the car in it.

My brother and I were talking about a picture we saw a while back.It was the underside of a racecar, we think probably a BMW.The bottom of this car was so well designed, everything was on a flat level plane. It had most of everything thing covered, except the steel tube framing and the exhaust. The exhaust looked either square/rectagle tubing or oval tubing. There were perfect channels in the bottom of the car to fit the custom welded exhaust in so it didn't sit any lower than the "skid plate". They also exited the side of the car as far as I could tell.This is an idiotic long shot but we can seem to find this picture we thought we'd saved. We figured if we could find the pic we could easily figure out what car it was and the detail about that car. We just can find anything...Thanks for any help. via /r/cars http://ift.tt/2t3hnH8
