Product Details

The Magnaflow 551076 is a California-legal universal catalytic converter designed for 2.50-inch inlet and outlet exhaust systems. Built to meet strict California Air Resources Board (CARB) emissions standards, this converter is compliant for use in California and all other U.S. states, making it one of the most versatile aftermarket catalytic solutions available.

Magnaflow universal catalytic converters are constructed with a high-flow, stainless steel body and feature a premium ceramic substrate coated with platinum and palladium catalyst materials. This design maximizes exhaust flow while efficiently converting harmful emissions — including hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) — into cleaner byproducts.

Key Features:

  • 2.50-inch inlet and outlet diameter for a wide range of applications
  • California Air Resources Board (CARB) compliant — legal in all 50 states
  • High-flow ceramic substrate for improved exhaust efficiency
  • Stainless steel shell for long-lasting corrosion resistance
  • Platinum and palladium catalyst coating for effective emissions reduction
  • Universal design for flexible installation on custom or replacement exhaust systems
  • Meets or exceeds OEM emissions performance standards

As a universal-fit converter, the Magnaflow 551076 is intended for custom installation and may require welding or the use of appropriate connectors for proper fitment. It is an ideal choice for builders, fabricators, and mechanics seeking a reliable, emissions-compliant catalytic converter for performance or replacement exhaust builds.
