Pontiac Grand Am Catalytic Converter - Rear - Magnaflow - OEM Grade OBDII Direct-Fit - `04-`05. A direct-fit rear catalytic converter designed to replace the factory unit on 2004–2005 Pontiac Grand Am models, offering OE-style fit and EPA-focused emissions performance.
This MagnaFlow OEM-grade converter is engineered to match original equipment flow dynamics and fitment using modern metrology and spun-body construction. The direct-fit design requires no cutting or welding for most installations and includes the gaskets and hardware needed to help prevent exhaust leaks. Constructed with corrosion-resistant stainless steel and mandrel-bent tubing, it aims to retain factory exhaust geometry for consistent engine operation and fuel efficiency while meeting Federal EPA standards for OBDII applications. Note that this unit is not CARB-certified and local emissions regulations may affect sale or installation.
