hi i have 2 k&B .40 engines and i was planing to build a cessna skymaster.
the thing is that my engines has no muffler, and i need to build a semi scale muffler (l saw one instaled on a cessna 182, with the 2 exaust pointing down)

if someone has any idea of building one or if there's any kit to be adapted, please e-mailme to instructor@fibertel.com.ar or postit here.
