Returning Visitors
If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

-the right one:
the bumps or ripples in the cone are likely discs with holes in the centre used to align one or more pipes in the baffle.....
if the baffels were held in place just by the tail end of the pipe vibration and bouncing conmined with corrosion would make the internal fall apart rahter quickly.....
do you see any spot welds anywhere on the underside or inboard side of the mufflers?

Yes.. you are right. I was afraid they turn out to be like that. The Yamaha had a middle disc for alignment. It had a 3-tube system connected trough a disc. However this EFE seems to have more discs and I'm quite afraid of what I might find inside.
I attach 2 more pictures with the "dots" (for welding I suppose). There are 2 small holes (one of which is visible in picture 1).
There would be an option to cut the "tubes" in length, where they were joined (the long line in the middle). It would prove maybe a little difficult to weld them on such a length; still have to think about that. If I do that I might end up deforming the tube when I'll have to crack it open to let the elements inside come out.
It's such a pity no one has done such an autopsy.
The pics (last ones I hope before the surgery):

and second picture (upside-down... sort of):
ok so i took a grinder ot my old pipes in order to have a buddy practice welding on them
I really doubt if Suzuki reinvented any assembly processes so mine are likely a good example of what they did in all....
mine had the end pieced rollled in
i cut away a panel encompassing the outer perimeter of the spot welds
and lo and behold the three pipe baffle core came out ( it had rusted off the exhaust end or broken due to a support disc coming loose.
sadly this is your production set of pipes and going at them with a grinder is tedious at best
I only did mine cos they were throw aways and I needed a real world welding problem......
OK guys someone work for the FAA got a set of these they can get x rayed?

"In the back of the exhaust is a plate rivetted in (four rivets) it's connected to a tube about 100-120mm long, this slides into another plate, it's an empty chamber, if it's rattling drill out the rivets then rotate the plate, drill new holes and re rivet...Make sure there's no leaks in the collector box or when you shut off from high revs it'll blow the baffles out"
It's not the rivets or that tube that are making noises.. but something from the interior..
