MagnaFlow from Napkin to Truck

Gary S. Vasilash

We are big fans of back-of-the-napkin thinking, so when we saw this, we couldn’t resist sharing it with you:


What you’re looking at is, yes, a napkin. It was penned by Richard Waitas, senior manager of MagnaFlow, a provider of performance exhaust systems. He was sitting in an airport, waiting for a flight, and started thinking about the ideal sound of a 1949 Chevrolet Truck.

“What’s deep, what’s raspy, what’s throaty, and what’s not is different from ear to ear. ‘Loud’ has many levels and characteristics. But with the launch of the Revolver Truck”—which is the ’49 sketched—“MagnaFlow has found a way to provide an answer to the question,” Waitas said.

And the answer, which Waitas found working with Chip Foose, was a system that has eight rotating mufflers.

That’s right: Eight rotating mufflers.

While that provides the means by which it can be on display at SEMA later this month (in booth 23543), if the revolving mechanism is removed, the Revolver can be driven on the street or track.

All of which is to say that it is a good idea to keep plenty of napkins at hand.
