Here=92s a question for = Chris, Paul, and others with knowledge of L2 exhaust.  My 360 = with Superior IO 360 is ready for engine start up.  The exhaust is = a 4 into 1 built by Sonic Headers in Princeton, Mn.  It = is beautiful work and ceramic coated.  Sonic provided me with = a clamp to fit over the large pipe (collector exit).  This = will need to be fastened to the underside of the fuse in some = manner, but I question whether it is necessary.  The collector is = bolted to two of the headers with stainless dogbones and 3/16 = bolts.  The headers are of course very solid on the block. =  The additional clamp would need to be rubber mounted to allow = engine movement.  I see no way the collector or any part of it = can ever depart the plane.  Is this clamp = necessary?

I have been flying my = O-320 with standard factory exhaust for over 1,800 hours without a clamp = and without any problems. I do have the 2 exhausts strapped together = with a stainless hose clamp over exhaust wrap. See post on 01/11/12 for = a photo.

I just have completed the = install of a 2 screen Dynon Skyview system with ap and Dynon txpd = with traffic, Garmin SL30 radio to give ILS presentation on the = Dynon screen.  I have no steam gage backups.  With dual = screens, backup batteries and dual ADHRS I feel that I have enough = redundancy.  Does anyone have input or comment?  This = plane may be one of the first with no round gauges = anywhere.

I like backup = steam.
