EXHAUST
1. GENERAL
This chapter describes those units and components which direct the engine exhaust gases overboard. The
engine exhaust system consists of exhaust headers, Y-pipe, midpipe, muffler, heat exchanger, tailpipe,
and associated slip joints and fasteners.
The exhaust system carries engine exhaust gasses directly from the engine exhaust ports to outside the
cowling on the underside of the fuselage. The system is a tuned design, meaning each of the six headers
are the same size and the overall length sized to provide optimum scavenging which results in maximum
horsepower and engine durability. All exhaust gas components are fabricated from stainless steel and
stainless hardware is used in all areas subject to high heat.
To provide hot air for cabin heat, a jacket around the heater muffler serves as a heat exchanger. For main-
tenance practices pertinent to the heater muffler, refer to 21-40 Heating and Defrosting System. (Refer to
