Is it illegal to modify a motorcycle with an Akrapovic exhaust?
2 Answers
Modifying the exhaust system of a motorcycle is illegal. According to Article 56 of the 'Regulations on the Registration of Motor Vehicles', the traffic management department of the public security authority may impose a warning or a fine of up to 200 yuan for any of the following circumstances: (1) The rear of the body or compartment of heavy or medium-duty trucks and their trailers fails to display the enlarged license plate number as required, or the enlarged license plate number is not clearly visible; (2) The application of markings or advertisements on the motor vehicle affects safe driving; (3) Trucks or trailers fail to install side and rear underrun protective devices or apply reflective markings on the body as required; (4) The motor vehicle fails to undergo safety technical inspection within the prescribed time limit.
Regarding whether modifying a motorcycle with an Akrapovič exhaust is illegal, I’d like to share my perspective based on riding experience. In China, exhaust modifications are generally considered illegal because national regulations stipulate that exhaust noise must not exceed 80 decibels and must comply with emission standards. Although Akrapovič is a well-known brand, many of its models are designed for high decibel levels, making it easy to exceed limits after modification. I once saw a friend fined 500 yuan for such a modification, which also affected their annual inspection pass rate. I recommend checking local traffic regulations first or opting for certified products to avoid major losses for minor gains. From a safety standpoint, excessive noise can disturb the public and increase accident risks, so respecting the law is the wiser choice. In short, think carefully before modifying—don’t break the law just for a cooler ride.
