WARNING: These pipes are not street legal in the United States to be run on DOT roads and violate the Clean Air Act which states vehicles in every State in the US must have federally compliant catalytic converters on them. We are selling these pipes to our race car customers for track use only on non-street legal race cars for use in sanctioned events. For EPA legal, high flow catalytic converters ask us about our Green Cat options.
