ORIGINAL: dupuisma

I'm using the Evolution EVO30943400 invert wrap around from Horizon Hobby. There is no discernable rpm gain with the silencer removed. I didn't use a tuned pipe because in pusher configuration the pipe would be exhausting forward.
Here are the real life data collected by me, some very interesting info on mufflers and special engine treating .
