Dave,
Boy you hang around a real group of character? Naa just kidding, nice guys them two. I haven't seen Rob in awhile though. I saw Elton down at Joe Nall. I haven't been able to make Bealton the last few years for varios reason, one being a surgery. Not suppose to have one of those during our short flying seasons. Hope I can go back soon though. Had fun there. Matt gave up flying this year and is planning on moving out to Vegas next month. What a waste of talent for now anyway ?
This cannister muffler thing has me ready to go and stay with the stock mufflers....Simple. Just don't have the handle on these mufflers yet, but working at it. Will be talking and looking at a few guys setups this weekend.

Dick, As I mentioned to Dave above, I will be talking with guys and looking at a few planes this weekend, so maybe seeing first hand and maybe measuring will help ? Thanks.
