On a track, though, you’re more likely to hear that sport exhaust before you see it. On the car’s first lap around Barber, everyone’s attention was focused on seeing what car was lapping. At speed, the Porsche’s pipes open up and the sound changes from refined sports car to snarling Germanic wail. Tim Cupp, Porsche’s product manager for sports cars, says the sport exhaust is available on other Boxsters, but only raises the volume. On the RS 60, it helps the car take advantage of a re-worked engine management system, which adds eight horsepower.
