Magnaflow Universal fit - Catalytic Converter fits Buick Regal 1990-1989

Compare MagnaFlow's catalytic converters with any other manufacturer and you'll see why MagnaFlow has become a leader in the manufacturing of exhaust components. Others may employ one or two of the following features, but only MagnaFlow puts them all together to create a catalytic converter that exceeds basic need and function. Our years of research and development have resulted in many unique features that are exclusive to MagnaFlow. We combine efficient manufacturing techniques and state-of-the-art industrial design to produce an end process and product that sets, rather than meets, the highest standards of product performance and efficiency in the industry. The 91000 series universal is designed for use with small to medium sized engine displacements where space is limited.
