Where is the drilling position on a motorcycle exhaust pipe?

[Hubert]

Motorcycle exhaust pipe drilling is generally done at the lowest point of the exhaust pipe. Pros and cons of drilling: Drilling holes in the exhaust pipe slightly reduces exhaust resistance, but it does not significantly improve power output. Additionally, it increases exhaust noise and does not reduce engine heat, offering no real benefits. Normal engine heating: Engines naturally get very hot during normal operation, which is nothing to worry about. As long as the engine oil and lubrication are functioning properly and the riding technique is correct, there is no cause for concern. Introduction to motorcycle exhaust pipes: They primarily use sound wave interference principles for noise reduction. Inside the exhaust pipe, baffles and tubes separate the sound waves. As the exhaust passes through these baffles and tubes, the sound gradually weakens. At the outlet, the sound waves are collected into a single tube to interfere with and cancel each other out, reducing noise by overlapping the rarefaction and compression phases of the sound waves.
