Nearby buckle's U back pressure drum: Main promot high speed horsepower and middle and slow-speed of revolution torsion. The sound is quite fastidious. The drum body is designed to increase a horsepower and reduce the volume. Walks on the street and high speed, no matter what chooses. Sound about 85 decibels. The good a vehicle race and best quality goods. (U back pressure drum. The outward appearance is attractive. Nearby buckle baking varnish. The vehicle performance is very good)
