Chevrolet Monte Carlo Catalytic Converter - MagnaFlow - California Grade CARB Compliant (2004–2005). This direct-fit replacement is engineered to restore proper emissions control while maintaining original exhaust flow and fitment for the 2004–2005 Monte Carlo (also listed for select 2004–2005 Impala applications).
MagnaFlow part 5461532 is a spun-body, direct-fit catalytic converter designed and developed using 3D metrology to match OE contours and mounting points. Constructed from high-strength 16-gauge 409 stainless steel with mandrel-bent tubing, the unit resists corrosion and preserves factory exhaust geometry for consistent engine performance and fuel economy. The single laser fusion weld reduces potential leak paths and the compact, low-mass design improves thermal efficiency. Installation is straightforward with included gaskets and hardware; no cutting or welding is required when installed with proper tools. This converter meets California Air Resources Board requirements for the listed vehicles and is legal for sale in all 50 states when used per its CARB Executive Order—installation is permitted only if the vehicle’s EO and Engine Family Number appear in the converter’s CARB Executive Order.
