4 in 1 exhaust system with four primary tubes of 805mm length joined in a manifold and a tail pipe. A rotating tube allows to absorb the mobility between the primary Exhaust and the Silencer installed under the cockpit.
The respect of the identity of the lengths of the primary tubes allows an equivalent output for each cylinder, bringing a gain on the fuel consumption (approximately 10%) while decreasing the engine vibrations for a better comfort inside the cockpit.
The thermal recovery of the exhaust gas flow supplies the carburetor and the cabin heater. Carburetor heater and cabin heater boxes installed respectively on the primary and tailpipe manifolds.
The choice of materials with high thermal resistance ensures excellent reliability.
A revision of the Silencer is required every 600 hours for the necessary inspection of the soundproofing materials.
