The MagnaFlow California‑grade direct‑fit catalytic converter for 2004–2005 Pontiac Grand Am and 2004 Oldsmobile Alero replaces the factory unit to help keep the check engine light off while maintaining exhaust flow. Mandrel‑bent tubing and corrosion‑resistant stainless steel replicate OEM flow dynamics; the spun‑body design and laser fusion weld reduce leak potential. Included gaskets simplify sealing, and the converter is CARB‑tested for legal use in restricted states for the listed applications.
