This listing is for a Knisley Welding Right-Hand Muffler Assembly, Part Number K156020-2, designed for use on Cessna 200-series aircraft including the Cessna 210 Centurion series and related 206/207 platforms. This component forms a critical part of the aircraft engine exhaust and heat exchange system, helping to reduce exhaust noise while directing exhaust gases safely away from the engine compartment and surrounding airframe structures.
The muffler assembly is manufactured by Knisley Welding Inc. of Loomis, California, a well-known FAA-approved manufacturer of aircraft exhaust components and PMA replacement parts used widely across general aviation aircraft. The unit is constructed from high-temperature corrosion-resistant aviation-grade stainless steel, designed to withstand extreme exhaust gas temperatures and vibration loads typical of piston aircraft engines.
This particular unit is new surplus, meaning it has never been installed on an aircraft but may show minor storage marks from shelf storage. The exterior finish and weld seams appear clean and intact, with no evidence of operational heat discoloration or exhaust residue.
The muffler includes the exhaust canister body, welded seams, inlet/outlet connections, and mounting flange, allowing it to integrate directly with the aircraft exhaust collector and tailpipe system on compatible aircraft models.
