RE: 3W-50i and G62 with 22x10 props
I don't see how it can , because it's just a header into some straight pipes with stacks, but you never know. I ran some tests this summer and compared them to another flier on RCU who was running a Johnson pitts style muffler. My numbers were about the same as his. I do have a Johnson Pitts muffler for my 3w-50i, so maybe I'll try it out one of these days.
I'd be interested to hear what other folks have been getting with the same prop.
