Yeah, that is a bitch. I can't tell you how many bottles of Meguiar's Scratch-X I've gone through removing the carbon residue that clings to the bumper of my RX. I had to extend the muffler over an inch to help reduce it.

So, through testing they now have the current configuration of quad stacked exhaust tips with diffuser panels around them and air foils under the trunk belly. This significantly changes the air flow in that area of the car and made it much more stable at high speeds.

That's pretty interesting, I found a picture of the shroud around the stacked tips.
Definitely an ingenious solution to their turbulence problem.
But back to the FR-S, I really hope they don't have quad exhaust tips. A dual exhaust on a 2.0l 4cylinder is stretching it as it is, please don't screw the car's aerodynamics up so much that you have to resort to the same sorry solution as the IS-F. Although, it really doesn't matter. I hope to have the factory exhaust on ebay within a few weeks of owning it anyway.
