No, MotoGP bikes are not straight-piped. Straight piping refers to the practice of removing the muffler or exhaust system from a vehicle, resulting in a loud and unrestricted exhaust note. MotoGP bikes, on the other hand, are equipped with complex and highly engineered exhaust systems that are designed to optimize performance while complying with noise regulations.
The exhaust systems on MotoGP bikes incorporate various components such as headers, catalytic converters, and mufflers, all carefully designed to enhance power delivery, manage exhaust gas flow, and maintain acceptable noise levels. These bikes undergo strict technical inspections, including noise testing, to ensure compliance with the regulations set by the Fédération Internationale de Motocyclisme (FIM), the governing body of motorcycle racing.
While MotoGP bikes do produce a distinct and powerful sound, it is achieved through advanced engineering rather than simply removing the exhaust system.
