No, have not tried it. I will stick with the basic muffler. Looks nice, and if I flew at a field that had noise problems I would buy it. No power gain and more weight so I will pass.
I see the new Vision is on his site, new colors, and its now only 495.
I dont feel too bad, I got mine for 525 this winter at Chief, but still, be nice if they came down in price. The DV also dropped. Might have to get one of those this summer. Toledo is going to be expensive again this year! haha.
