In addition to BMW X5 Sports' pictures of the Esso Supra, here is one of the right side showing carbon build up from the exhaust (ie. the black stuff), and finally a shot of the left side of the car. Looks like it's just on the right side.Izanagialso, quick question but does the Esso Supra have the side exhaust on only the left side or does it have one on the right side too? J/W
