These attractive, quality exhaust mufflers feature a rugged,
heavy-duty construction. The top and bottom covers are cast aluminum with a metal
perforated housing for heat resistance. The tie rods and nuts are zinc-plated steel. At an
in-line pressure of 90 psi, these mufflers reduce the noise level by 17-22 decibels with
little impairment of operating efficiency. They are supplied with NPT male connections.
