All kinds of resonances set up, esp. in small, lightweight vehicles.My motorcycle, for instance, sets up a buzz at about 58 mph, fairly narrow band, and then it's gone. I think it's related to the CV automatic tranny, but whatever it is, it comes with the territory. I'd rather have low, thrumming noises than rattly or high-frequency buzz noises, but I'd rather have no harmonic vibrations at all!If they moved the cup holder back, you'd keep hitting it with your elbow! Maybe a smaller, Mazda Miata type of shifter would be better... It doesn't need to be so tall. Then it wouldn't be so awkward getting to your drink.
I agree with the sound. I hope it doesn't drone on at highway speeds.
There are lots of things involved, but exhaust tuning is one of the biggies. I'm concerned that the side exit on the exhaust will set up a medium low whistle, like blowing across a coke bottle -- and if you go too fast, it will jump an octave! (Try overblowing a flute, or your coke bottle for that matter). It's the sort of noise that cannot be detected except by road testing.
