Magnaflow 2003 Chevrolet Impala 3.4L Direct Fit Converter

MagnaFlow is known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter, part number 4561532, is built to keep your 2004-2005 Buick Century running cleanly and legally, especially if you're in a state with strict emissions requirements like California. It's designed to replace your original converter without needing any cutting or welding, making the installation process much simpler.

This converter uses free-flowing, mandrel-bent tubing to help your engine breathe easier, which is key for maintaining performance and fuel economy. The body is made from corrosion-resistant stainless steel, and MagnaFlow uses a single laser fusion weld, replicating the OE spun body design to greatly reduce the chance of exhaust leaks. They also pay close attention to thermal efficiency with a compact, low-mass design. MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the factory part it's replacing.

To make installation as straightforward as possible, this converter comes with the necessary gaskets, including a flange gasket and a crush ring gasket, to help ensure a proper seal. This part meets or exceeds California Air Resource Board (CARB) requirements and has passed additional testing for legal use in California and other CARB-restricted states for the vehicles it fits.
