After 1900 hours on the aircraft, my left side exhaust pipe has cracked from fatigue and will require substantial repair.  I am looking to purchase a new left-side exhaust system (cylinders 2 and 4) for my Lancair 320 with a carbureted O-320 engine.  The original Lancair part number is EX-3/4-C.  If anyone has an exhaust system they are willing to sell please contact me.

After disassembly of the exhaust system, I also found a crack on the right side exhaust as well (although small and repairable).  I did not support the aft end of the exhaust system pipes near the firewall as recommended by some.  I now believe that for longevity, this is required.  I will be fabricating a hangar system for the exhaust pipes.  Any pictures of this type exhaust system hangar assembly is greatly appreciated.
