Here is the picture from Andrew's email.
My exhaust is stupid loud. I've tried a few things which didn't work. Getting noise complaints around the airport while testing.
Just reading this Gary Schwarz's link, looks promising. Andrew, did you fit yours inside the cowl? I'm surprised 5mm endplates are holding up.

Kelly, I would if I had some, really did not expect it to work as I deviated from the design a bit. Will be back at airport on weekend to take photo, too late for construction photo. But nothing to it.
I read about the idea by Gary Schwarz in this
thread, post #7 , post #58 for his testing and post #142 sums up his findings.
Someone on here may know him as he was doing it for a rotary. Mine is much shorter than his drawing below due to space constraints but the theory works.
edit: Ahh!!! deleted his picture as too big to post. it is in his post #7 mentioned above though.
