Magnaflow 49 State Direct Fit Catalytic Converter Reviews
Part arrived packaged well. For the price there was no triangle flange gasket included and no bolts, washers, or nuts (no additional hardware). This part is not cheap, everything should be included. Actual installation went fairly well, either the flange on this or the flange on the Magnaflow Catalytic Converter was offset. The two Magnaflow parts did not line up correctly.
