Six Mazda rotary sections bolted together into a straight 6 rotary. Sounds pretty interesting. Crazy Kiwis. Stuck it into an RX4.

Well it is a race car, kind of, so muffling wasn't a priority.
Don't know if you guys were into racing in the 1970s, but when the rotaries first hit the track, they were among the loudest cars on the track (although I knew of one outboard engine powered sports racer that rivaled them). They were subject to engine vibration that actually shattered the exhaust pipes - you'd see them after a race and it looked like something had started to tear the pipe. They ended up using a much heavier gauge of piping (the rest of us understandably objected to having to drive through a minefield of Mazda exhaust parts ejected from the cars as they ran).
We could follow them all the way around Westwood, our local track, even down the back straight, just by ear.
