Dorman 672-603 Catalytic Converter with Integrated Exhaust Manifold CARB Compliant

The Dorman 672-603 is a direct-fit catalytic converter with integrated exhaust manifold designed for select Nissan and Suzuki vehicles. This combined unit replaces both the exhaust manifold and catalytic converter in a single assembly, simplifying installation and reducing labor time compared to replacing components separately.

Key Features:

• CARB compliant for legal use in all 50 states including California
• Made in USA with quality materials and construction
• Integrated design combines exhaust manifold and catalytic converter
• Direct-fit replacement for OEM part, engineered to match original specifications
• Pre-welded assembly reduces installation complexity
• Includes necessary gaskets and hardware for installation

This manifold converter assembly is engineered to restore exhaust system performance and meet emissions standards. The integrated design eliminates the manifold-to-converter connection point, reducing potential leak points and improving durability. Ideal for vehicles that have failed emissions testing due to catalytic converter failure or for replacing cracked or leaking exhaust manifolds.
