Emissions Notice — Depends On How It Is InstalledThis is a universal weld-in crossover pipe, not a bolt-in cat-delete section. If it is welded in place of the factory catalytic converters, the vehicle no longer carries its complete emissions system: it will not pass an emissions or OBD inspection, it holds no CARB Executive Order, and it is not legal to operate on public roads in the United States. Installed downstream of the factory catalytic converters with the cats left in place, it removes no emissions equipment. Where it goes is decided at installation — the buyer and installer are responsible for compliance with all federal, state, and local emissions law.
