Note:
The sound level varies by size. The higher the number, the louder the sound. It is best to confirm the inner diameter of the exhaust port before purchase. If the whistle diameter is greater than or equal to the inside diameter of the exhaust pipe after 1CM extension, it will not be installed. Also, keep in mind that the volume of sound is related to the tailpipe propulsion and personal perception. After installation, the sound felt too loud or too small can not be used as a product quality problem. Individual models may have less propulsion or modified taildrum. Low or no sound, this situation cannot be used as a quality problem, please note!
