Comparing the serial exhaust systems from any standpoint to the sport systems not much identities are found. Neither their operation principle, nor their design factors and dimensions conform to each other. The cause of it lies partly in matters of expense, partly in matters of durability. It is a fact - to begin with drawbacks - the life the tuned up car is in any case shorter than that of a car of basic construction. The principle of output increase is different from the other systems; here the main point lies in preventing suction-over of the cylinder charge, greatly impairing the efficiency of engine, so that the smoke of the cylinder pairs working in separate strokes meet only in the open air, so a less throttling can be allowed for the engine at higher output.
