The Taildragger Aviation C-150 Exhaust STC gives you the authority to install one set of Cessna 150 exhausts on one specific Cessna 120, 140 or 140A with a C-85, C-90 or O-200 engine. This is a one time use STC, is N number specific and is NOT transferable. 

The STC includes paperwork and installation instructions. The STC is paperwork only, and does not include the exhaust or installation hardware. For a list of possible Exhaust suppliers, see the Muffler Sources page.

The cost of the STC is US$100 for International Cessna 120/140 Association Members, and US$150 for non-members. (Membership in the Association is only US$25 and you can join online at www.Cessna120-140.orgDirect link to the store)
