For Richard Leroy: The engine setup is what determines which side of the car the exhaust runs down.

For all Pierce straight 8’s, the exhaust manifold is on the right side, the passenger side of the engine. The exhaust runs down the right side of the chassis, inside the frame rails.

On the ’25-’28 Series 80 and 81 cars, the exhaust manifold is on the left side, the driver’s side of the engine. The exhaust runs down the left side of the chassis, inside the left frame rail.

A second layer of steel can be wrapped around a muffler to deaden the ‘ring’ from the muffler’s single thickness skin. Brazed or welded onto to the muffler. It definitely makes a difference in the sound of the car when running. Much less ‘radiated’ sound from under the car.
