They can't be the exhausts, they break this rule:
The entire circumference of the exit should lie on a single plane normal to the tailpipe axis and be located at the rearmost extremity of the last 100mm of the tailpipe.
(part of 5.8.3)
Does "normal" mean perpendicular then? Because I don't see how they do unless it does - I take it to mean the exit must have one face only, no shaping.
It means that it's normal vector (a vector perpendicular to the plane) must be parallel to the direction of the tailpipe axis. It's the "lie on a single plane" part that it seems to violate though – unless it's an optical illusion, it seems to curve over the surface there.
