I am somewhat perplexed about the advantages and disadvantages regarding the performance of engines with free-flow exhaust. Specifically in the '50s and '60s, free-flow exhaust emphasized "let it ...
A free flow system allows the spent gas to exit the vehicle more efficiently by changing the pipes used in the system and installing an intercooler between the engine and the exhaust. Benefits With a free flow exhaust system, a smoother removal of spent gas is offered.

A free flow exhaust has minimal obstructions thereby offering a more efficient way to scavenge the burnt exhaust gases.
