what should my rpms be on the 90lx with an 11X8 apc prop with the toni extensions?

With the extention kit.... should be somewhere around 14,500 . Looks for over 14K Drops a bit due to extensions --- the LX muffler was actually developed for the 90L to get back the loss from the toni extensions so it would run at 14,000+ again. Also, with the extensions, you try an 11x9 or 12x6 on the toni - when time/props permit
