For the universal drum 16, simply speaking, the higher the engine speed, the louder the exhaust pipe sounds, but only if the exhaust pipe is improved. Each brand of modified exhaust pipe has different characteristics. For example, "Scorpio" can greatly improve the power output when the engine is in a high-speed state. And at low speed, the torque loss is more serious than the original exhaust. Moreover, although the modified exhaust of Yoshimura brand does not have the power of "Scorpio" to greatly improve the engine speed, it can give attention to the power of improving high and low speed, and the sound is much lower than that of others.

In fact, for sports cars and street cars, power output and torque output are equally important, but most riders in China still pay more attention to the design of sound and shape. Generally speaking, we are looking for some test data, comparing the output differences of different exhaust pipes, so as to choose our own suitable model instead of blindly expensive one. Old brands such as Yoshimura have rich product lines, affordable prices and many styles. As far as workmanship is concerned, Scorpio is indeed more refined, but it is expensive.
