MagnaFlow 5551444 California Grade CARB Compliant Manifold Catalytic Converter

The MagnaFlow 5551444 is a California Grade CARB-compliant direct-fit manifold catalytic converter engineered as a precise OEM replacement. Built with fully stainless steel construction — both body and tubing — this one-piece, spun-body converter delivers long-lasting corrosion resistance and reliable emissions performance.

MagnaFlow's advanced metrology department employs state-of-the-art 3D scanning technology during research and development to guarantee OEM-like fitment. The single laser fusion weld replicates the original equipment spun body design, significantly reducing the risk of exhaust leaks, while the compact, low-mass construction promotes greater thermal efficiency.

Key Features:

• CARB Certified — Meets or exceeds California Air Resources Board (CARB) emissions requirements; legal for use in California and all CARB-restricted states
• Direct-Fit Design — Bolt-on installation with no cutting, welding, or modification required
• Stainless Steel Construction — Corrosion-resistant stainless steel body and tubing for maximum durability
• Mandrel-Bent Tubing — Free-flowing pipe design for optimal exhaust flow and efficiency
• OEM Spun Body Design — Single laser fusion weld minimizes leak risk and mirrors original equipment construction
• Ceramic Substrate — High-efficiency ceramic catalyst substrate for effective emissions conversion
• Flanged Inlet & Outlet — Factory-style flanged connections with 2 oxygen sensor ports
• Converter Body Length: 5.675 in. | Overall Length: 30.875 in.
• Includes: 2 flange gaskets and 2 nuts — all hardware needed for installation

This catalytic converter with integrated exhaust manifold is certified by CARB for legal use in California, Colorado, and all other CARB-regulated states. The included inlet and outlet gaskets help ensure a proper, leak-free seal during installation.
