This custom stainless exhaust system was designed specifically for the Cozy Mark IV aircraft.
For Lycoming O-235 to O-360 (180 HP or less) use PN 33702
For Lycoming IO-360 (200 HP) Angle Valve Engine PN 33702-1
For Replacement Cozy Extension Spring use PN 33704
For Lycoming O-235 through IO-360 (200 HP) Cozy 4pipe exhaust manifolds (inside the cowl type) PN 08-07342
At 250 hrs of operation on my IO-360 powered Cozy IV the slip joints at the exhaust flanges are leaking badly and it is already time for a new system
