Pontiac GTO Catalytic Converter - Magnaflow - California Grade CARB Compliant Direct-Fit - `05-`06. This direct-fit replacement (MagnaFlow part 4561033) is designed for 2005–2006 Pontiac GTO 6.0L applications and intended to restore proper emissions control and prevent check-engine light triggers.
Built to match OEM fit and flow characteristics, this MagnaFlow California-grade converter uses precision metrology and OE-style spun body geometry to provide reliable performance and fitment. The compact, low-mass design aids thermal efficiency, while the replicated OE flow dynamics help maintain factory engine operation and fuel economy. Installation is simplified with included gaskets and hardware; the direct-fit design generally requires no cutting or welding when installed with the correct tools. This unit is CARB tested for use in California and other CARB-regulated states but requires that the vehicle’s Executive Order (EO) and Engine Family Number (EFN) appear in the converter’s CARB Executive Order for legal installation.
