Pontiac Aztek Performance Exhaust - Magnaflow - California Direct-Fit Catalytic Converter - `04-`05 is a CARB-compliant direct-fit replacement designed to restore proper emissions control and keep the check engine light off. This unit fits 2004–2005 Pontiac Aztek applications and installs using the factory mounting points without cutting or welding.
Built by MagnaFlow with OE-style flow dynamics, this converter uses precision 3D-scanned dimensions and a spun-body design with a single laser fusion weld to minimize leak points and improve thermal efficiency. Constructed from corrosion-resistant stainless materials and featuring mandrel-bent tubing, it preserves factory exhaust flow and engine operation. The converter ships with the necessary gaskets and hardware for a proper seal and includes Torca AccuSeal® clamp technology where specified to help prevent pipe distortion while maintaining serviceability.
