Default Exhaust pipe crack !

Hello guys,

While checking my RV-4 engine, I've discovered on both sides of my exhaust pipes a crack over 270°. I've managed to get it repaired, but I'm now trying to find out a new way of fixing them, so they won't crack again. What kind of tail pipe mount would you advise?
Thank you all for your help and enjoy your flights!
Sincerely
Jean

4 pipes? Crossover?

My snowline crossovers were under-supported aft at the exits.

I think the aft cylinder exhaust flanges were the pivot point and the forward cylinders cracked at the exhaust flange welds.

Have Clint's 1.5" system now, including proper exhaust pipe suspension.
