[Land-speed] Two stroke exhaust connections

[Jim Dincau]

Hi all,
      Has anyone out there had any experience building two stroke engine 
exhaust pipes? Specifically attaching the exhaust system to the cylinder 
barrel. The standard exhaust on the engine we are running uses a ball and 
socket joint held together by springs at the barrel. We would like to run a 
more gas tight joint but are worried about stress on the barrel. Any 
comments?
