    The stinger's length and inside diameter are based on 0.59 to 0.63x the header pipe diameter and its length is equal to 12 times its diameter, depending on the results to be achieved. In a well designed tuned exhaust system, the total increase in pressure is in any case much less than the one produced by a muffler.

    en.wikipedia.org/wiki/Tuned_exhaust

    Tuned exhaust. Ferrari V10 engine showing one of its two tuned extractor manifolds. In an internal combustion engine, the geometry of the exhaust system can be optimised ("tuned") to maximise the power output of the engine. Tuned exhausts are designed so that reflected pressure waves arrive at the exhaust port at a particular time in the ...

  4. Exhaust system - Wikipedia

    en.wikipedia.org/wiki/Exhaust_system

    An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of the following: Cylinder head and exhaust ...

  5. Scavenging (engine) - Wikipedia

    en.wikipedia.org/wiki/Scavenging_(engine)

    Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next cycle, leading to reduced power output.

    Kawasaki KIPS. Kawasaki uses a power-valve system called KIPS (Kawasaki Integrated Power Valve System) on their two-stroke bikes. The KIPS utilizes both alterations in port height, closing of the secondary port ducting, and a resonant chamber. KIPS is operated by a mechanical governor on single cylinder machines.
