Pontiac Sunfire Catalytic Converter - Rear - MagnaFlow - HM Grade Direct-Fit (OBDII), Stainless Steel - `04-`05. A direct-fit rear catalytic converter engineered to restore proper emissions control and maintain factory-like exhaust flow for 2004-2005 Sunfire models.
This MagnaFlow HM Grade converter is built to replicate OE fit and function using mandrel-bent tubing and a spun-body design with a single laser fusion weld to reduce leak points. Constructed from corrosion-resistant stainless steel, it’s designed for straightforward bolt-in installation with the included gaskets and hardware—no cutting or welding required when replacing the rear unit. This part is intended for OBDII federal/EPA-regulated vehicles. Not legal for sale or installation in California, Colorado, or New York.
