I bought this -8A three months ago. (Not getting a nit-picky Condition Inspection-type prebuy was my mistake, but that?s another topic. At least I?m learning valuable lessons and next plane purchase will be better.)

Shortly after bringing it home, I found this:

Edit: Photo not showing - I?ll find a different photo hosting site that doesn?t require membership to view.

The Adel clamp on the right exhaust bracket (Vetterman exhaust) was broken. I replaced the clamp, and today found it broken again. The left side is intact and doesn?t show any problems.

What do I need to do for a permanent solution? Entirely new exhaust bracket system? Re-do parts of the existing one?

No picture, but the exhaust brackets need to be secured to the ENGINE, not the mount or the airframe. This may be your problem.

Ah, copy that. This bracket is a horizontal tube, crimped at each end, and secured to the engine mounts with loosely-fitting Adel clamps so that it can slide vertically. The crosspiece is attached to the exhaust pipes with Adel clamps.

Probably 100's of threads on broken exhaust hangers. Here's just one: http://www.vansairforce.com/community/showthread.php?t=131813

I like to search for topics on VAF with google site search: site:vansairforce.com vetterman exhaust. Change "vetterman exhaust" to any search term you want. Broken Exhaust Hanger also gives many discussions

Simple fix is to replace the flattened steel tube with solid aluminum rod. 800 hour or so with this fix and still going. Just drill a hole all the way through the rod for adel clamp bolt.
