isaacslaw ... I planned to install my YS110 and slimline pitts....... But it wouldn't fit
without mods so I went ahead and used the stock muffler. With the YS all the way
forward on the stock mount, my set up needed about 1/4" more room with the YS
inverted.. It may have worked side mounted, but after 7-9mos in the box I was a
bit in a hurry to fly her....
