Hello Bax,
I have an OS FT160 MAGNUM engine that I am putting in a TF Stinson Reliant. It fits fully inside the cowl. I have two questions, Are the exhaust pipes that come with the engine adequate or is there some type of muffler system I need to purchase. The second question is : if the pipes are adequate then are there some kind of extensions I can purchase to dump the exhaust outside the cowl? Thanks in advance Smitty
