The MagnaFlow Standard Grade direct-fit catalytic converter replaces the OE part to restore emissions control and limit check-engine faults on select Buick and Oldsmobile models. Mandrel-bent tubing preserves OEM flow and 409 stainless construction resists corrosion; included flange gasket helps avoid exhaust leaks. DIY installation is possible without cutting or welding for 1981–1987 Buick Regal and 1984–1988 Oldsmobile Cutlass Supreme applications.
