Cars without exhaust pipes can theoretically drive short distances, but they carry serious legal risks and technical hazards. From a technical perspective, the absence of an exhaust pipe causes an imbalance in engine back pressure, which may trigger fault codes in the electronic fuel injection system and affect power output. Additionally, the unmuffled exhaust noise may exceed 90 decibels, violating the vehicle noise limits stipulated in Malaysia's *Environmental Quality Act 1987*. Legally, according to Section 14 of the *Exhaust Emission Control Regulations*, unauthorized removal of exhaust pollution control devices constitutes an offense, punishable by a fine of 500 ringgit. If this results in excessive emissions, under Section 8, the vehicle may be required to undergo mandatory repairs or even be scrapped. Notably, even if the vehicle circumvents emission tests through modifications, traffic police may impound the vehicle under Section 64 of the *Road Transport Act* if they detect the missing exhaust pipe during roadside inspections. Furthermore, insurers may deny accident claims on these grounds. Vehicle owners are advised to routinely inspect their exhaust systems and exclusively use components certified by Malaysia's Department of Environment (JAS) when replacing corroded parts to ensure compliance with Euro IV-equivalent emission standards.
