Transforming the universal drum into the primary project for modifying cars. On vehicles with high performance requirements, the exhaust pipe is very important for the power output curve, and in vehicles that value individuality, the exhaust pipe is also a reflection of individuality. Moreover, the sound quality and modification have broken through the limit of noise (90 decibels). Although different places have different requirements, they have not exceeded the standard of 90 decibels. However, this kind of noise is very dangerous for motorcycles. Loudpipesavelife is an American language (its loud exhaust can save lives). In over 80% of motorcycle vehicle collision safety accidents, it is caused by the vehicle not paying attention. When our exhaust noise is loud, it is not necessary to argue endlessly about making vehicles pay attention to motorcycles and reducing the probability of safety accidents. Many motorcycle organizations abroad are applying to the environmental protection department to modify the terms based on this investigation report. Although considering the relationship between the two neighbors, we may temporarily not discuss this issue. If replacing the exhaust pipe, it is better to choose a loud noise from a safety perspective.
