Product Details

The MagnaFlow 6511128 is a California-legal, direct-fit catalytic converter engineered to meet strict California Air Resources Board (CARB) emissions standards. Designed as a bolt-on replacement, this converter installs using factory mounting points with no cutting, welding, or modification required, making it an ideal solution for California residents and those in states that follow CARB regulations.

MagnaFlow's California Direct-Fit converters are manufactured using high-grade stainless steel construction for lasting corrosion resistance and durability. The precision-formed housing contains a high-cell-count substrate loaded with premium precious metals to deliver efficient catalytic activity, helping to reduce harmful exhaust emissions including hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx).

Key Features:

  • CARB Compliant — Meets California emissions standards; legal for use in California and all CARB-adopting states
  • Direct-Fit Design — Bolt-on installation using OEM mounting locations; no cutting or welding required
  • Stainless Steel Construction — Highly corrosion-resistant for long service life
  • Premium Substrate — High-cell-count catalyst substrate for efficient emissions reduction
  • OEM-Grade Quality — Engineered to restore original exhaust flow and emissions performance
  • Check Engine Light Prevention — Properly triggers downstream oxygen sensors to keep the MIL off

The MagnaFlow 6511128 is a reliable, emissions-compliant replacement that restores your vehicle's exhaust system to proper operating condition. Built to OEM specifications, it provides a factory-like fit and finish while satisfying the most rigorous emissions requirements in the country.
