Although dual-mode exhaust systems aren’t exactly cutting-edge technology anymore, it’s not often you find them on Japanese luxury SUVs. F1 superstar Sebastian Vettel has lent his name to a special-edition Infiniti FX50, and to differentiate it from the run-of-the-mill Infiniti FX, the limited-edition, six-figure SUV is equipped with the aforementioned dual-mode pipes. We came across this amateur video of a couple of attendees of the 2012 Goodwood Festival of Speed that captured the limited-edition SUV running in both quiet and loud modes.
Admittedly, the rest of the video is fairly dull, but the demonstration of the two-mode exhaust system is worth a listen. And lest you think the exhaust is just a gimmicky geegaw for those that like loud noises, the Vettel-ized Infiniti FX produces 414 horsepower compared to the 385 produced by the regular Euro-spec Infiniti FX50. If you have the nerves and the stretch of Autobahn to do it, the Vettel-edition FX50 is reportedly capable of a top speed of 186 mph.
So, do you think the fierce exhaust note on the V-8-powered Vettel-edition FX50 justifies its six-figure price tag? Or would you be just as happy getting an off-the-shelf cat-back system? Take a listen below.
