Is Muffler Deletes Legal in Puerto Rico After the 2026 Framework Overhaul?

Yes, muffler deletes are legal in Puerto Rico if the vehicle complies with federal EPA noise standards (40 CFR Part 205) and local traffic regulations. Puerto Rico’s Reglamento de Tránsito (2023) aligns with U.S. DOT FMVSS 110, requiring exhaust systems to maintain noise levels below 92 dB(A) per SAE J1169 standards. Modifications must not exceed local noise ordinances enforced by the Policía de Puerto Rico and the Departamento de Transportación y Obras Públicas (DTOP).
