Don- sounds great about flying on Saturday- keep me in the loop and I'll try to make it out.

Regarding sound, the JMB's have been very quiet. Keep in mind, however, that these are just mufflers and are not supposed to provide any boost in power. I have a Menz 32-10 on it right now and I get a great deal of noise from the prop (tached at 5600-5700). I am contemplating going to a different prop to get the sound down- hopefully a 2 blade like an MSC 31-12. Haven't tried a 3 blade yet.

Regarding the tabs on the end of the pipe- I'm a bit surprise that other mfgr's haven't caught on to this yet. If one were included, a tab could be welded on.

Talk to you later
