I used to work as a corner marshal at SCCA races in the late 70s. I sure
remember those Mazdas -- had to wear ear protectors just because of them.
As for cockpit-switched exhaust cut-outs, heck, those were a common
accessory going back to the 1920s, I think. Seriously frowned upon for
street use, nowdays, of course.
