An exhaust system is provided for internal combustion engines which relatively improves the performance and reduces noise output of such engines. The system comprises a plurality of exhaust pipes which are operably flow connected to exhaust ports of the engine at one end thereof and to discharge pipes through a collection chamber at an opposite end thereof. The discharge pipes include a silencing device in the discharge ends thereof. A feedback mechanism is provided to divert a slip portion of the sonic wavefront and/or mass exiting through an exhaust pipe back toward the exhaust port associated with an interconnected exhaust port or in such a manner as to delay passage of the slip portion out of the discharge pipes or to delay the slip portion and direct same to a different discharge pipe for discharge. The feedback mechanism may be valve and computer controlled so as to add or delete the feedback as required to maximize operation of the engine and/or assist in operation of a vehicle powered by the engine.
