The velocity stack (horn) is something that many people might not care about in terms of engine power, but if you study the principle of operation of the actual engine, you will find that it is the part that can determine the engine torque as well. Or can increase the power of the engine in another way, apart from the exhaust pipe, which KSPP (has been researching and developing in this field for 3 years) is therefore reliable
