NOTE: This exhaust stack is 15" Tall and has a center slip riser PN 0750238-5AWL. This exhaust stack lacks reinforcement doublers at the engine attach flanges. Installation of the correct stack is critical to clear the intake air duct on aircraft. Where the exhaust is installed VIA SA00780NY upgrade STC the entire kit must be initially replaced. On aircraft SN 18256685 thru 18257608 both exhaust stacks must be changed at initial replacement as there is a change to increase the distance between the muffler shroud and the intake duct(Refer to Cessna SL67-37).
NOTE: This exhaust stack is designed for use on the O-470 Series engines only. Using it on IO-520, IO-550 or up-rated engines by STC will reduce the service life of the exhaust stack and may cause it to crack.
