of US competitions except National do not enforce noise level as long as the

use the muffler until you have enough to get a header &

<DIV><FONT face=Arial size=2>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</FONT></DIV></BLOCKQUOTE></BODY></HTML>
