Excellent compensation for the exhaust routing Steve. This is a perfect example of what I call "Proportional Shift".
Because of the change in scale and the difference in materials between the model and the actual car, the exhaust pipes seem to be half again as thick as they are IRL. And the torsion bars on the model look to be at least twice the diameter of their real world counterparts. If the model torsion bars were replaced with wire of the same scale diameter and the exhaust parts were similarly represented, then a builder might be able to route everything in a prototypical manner. But even then, one would need to consider the difference in materials. There is just no way that a 2.5mm diameter plastic rod will bend in the same way as a 2 1/2" steel tube.
I think you came up with an excellent solution to one of the oldest scale modeler's dilemmas.
