ys 1.20

They will work fine for you Shel. Pipes on 4 cycles engines do not boost power. They may not be as restrictive as some mufflers. In competition we want quiet and we need vertical performance. As long as you don't need long verticals you should have a ball.

  HI i'm hopefully going to be able to buy a used ys 1.20 for a couple 1.20 size planes soon.i've seen some 1.20's for sale with stock muffler,no header/pipe.can these engines be used with success using a stock muffler as opposed to header/pipe if the planes are not competition bound?i prefer using a 4st but will have to buy used due to my small budget,thanks in advance.........shel
