The local government of Valenzuela City recently held a ‘Ceremonial Destruction’ event, crushing 275 illegal mufflers in a rather eye-catching fashion. These open-pipe systems were lined up into two columns and then became the track marks of an excavator.
You heard that right. An excavator ran over these confiscated mufflers—sending a clear message to motorists who still use illegal exhausts. The construction vehicle was then followed by a smaller drum roller that further flattened the crushed metal. The job looked done until the excavator backed up for second licks and used its bucket to pound on the mufflers.
For the unfamiliar, open-pipe mufflers remove one or several components of the overall exhaust. These include the muffler itself, the collector, and the catalytic converters, leaving a short or long pipe connected to the engine. This is what creates an illegal and downright rude amount of noise.

It looks like open-pipe systems continue to be a problem for local governments and law enforcement. In January 2026, the Philippine National Police directed its regional offices and the Highway Patrol Group to enforce the laws and ordinances against illegal exhaust modifications.
This led to the Land Transportation Office (LTO) needing to clarify its guidelines on aftermarket mufflers. Essentially, while aftermarket products from authorized dealers are generally safe, riders need to be dutifully conscious of the modifications they make. Even if an aftermarket system passes the 99dB test, it can still violate other rules set by the LTO.
