Note:Different specifications make different sounds. The bigger the size of the whistle, the louder the sound. Please confirm the inner diameter of the exhaust port before purchase. If the whistle diameter plus 1cm is greater than or equal to the inner diameter of the exhaust pipe, it cannot be installed. At the same time, please note that the sound level is also related to the exhaust thrust and personal feelings. Individual models may have little or no sound because of the low exhaust thrust of the original vehicle or the modified tail drum.
