This design exhaust system was very common until the 1980s when 'water lift' mufflers became popular. The 'jackets' were usually made of heavy copper and the 'stack' was vertical with the 'injection' water entering countercurrent (from the top) into the 'stack' .... the price of copper eventually made such design very expensive.

The only real problem in such 'wet stacks' is when a pin hole developed between the wet side and the dry side the leakage wasnt 'visible' and eventually would 'back flow' into the engine ... the shut down and 'cooling' engine developing vacuum and drawing the leaking 'stack water' into a combustion chamber - ouch.
