Muffler for the Yamaha 130FI with 2" header pipe on Little Wing 5 tractor ????
I had a few bystanders yesterday during engine tests at the airport. Normally I'm wearing headsets or sound suppressors. The bystanders were not. They seem to think that the stock header configuration was pretty loud. I notice on the rotary Wing Forum you've had some discussions about mufflers, what was your final decision?
In my particular configuration, the header pipe comes straight down through the lower cowl half, at a very slightly rearward angle. I would have to make a disconnect there, on the 2-inch pipe and continue down and rear with a 90 and muffler. The 90 and Muffler combination would have to be removable so that I could remove my lower cowl.
Of course with any choice, size, streamline, weight and cost.
