Troubleshooting:
----You can use your mouth to blow hard on the air inlet of the tight whistle, if you can hear the whistle, it means the product is good.
----If it is installed in the tail throat and does not make a sound, it may be that the airflow of the car is not strong enough and the whistle is not concentrated enough to blow the whistle. It can be installed outside to use the wind. Because the airflow of the wind is stronger than the airflow of the car, it is easier to blow up.
Note: This product is only suitable for the installation of vehicles with a straight tail section of the exhaust pipe, and the exhaust pipe with curvature is not applicable.
