I seem to be forever replacing them. I'll try Johnathan's idea with the hope it works on my A/C. Worth mentioning that all for stubs have different lengths between the mounting loops. #1 being longest .Surely there should be an optimum distance for all the stub loops/box?

I note a lot of spring issues appear to be with the tension type.

The problem with CKT headers/tubes is that the attachment loops welded to them are closed i.e. they don't allow the compression spring loops to be hooked on. I wonder if there are compression springs with open hooks? Or maybe link the end of the spring and the closed loop with something?

Why not just try lockwire instead? And is it the expansion contraction of the loop itself that is possibly causing the fatigue crack?? If the loops have no set distance apart then spring tensions will be all over the place; so are the higher or lower tensioned spring loops cracking? Additionally there is no support fixing on many of these rotax 912 muffler boxes; all the modal energy generated is transfered directly through the header pipes; this is just nuts Read this topic online here: http://forums.matronics.com/viewtopic.php?p=507767#507767 ________________________________ Message 5 _____________________________________ Time: 08:21:20 AM PST US From: William Daniell Subject: Re: Europa-List: Re: CKT exhaust cracks i dont have anything on my Colombian homemade stainless exhaust joints.... no leaks William Daniell +1 786 878 0246 On Wed, Aug 24, 2022, 09:44 Area-51 wrote: > goldsteinindustrial@gmail.com> > > This is fascinating... outside the box; why even use springs?
