Product Details

MagnaFlow Universal Catalytic Converters deliver dependable emissions control and consistent exhaust performance across a wide range of vehicle applications. Engineered to meet or exceed original equipment (OE) standards, this product line reflects MagnaFlow's decades-long commitment to quality, compliance, and long-term reliability in emissions system repair and restoration.

Key Features:

  • Heavy-Gauge Stainless Steel Construction — Built tip-to-tip from premium stainless steel for superior corrosion resistance and long service life, even under demanding thermal conditions.
  • Ceramic Monolithic Honeycomb Catalyst Substrate — High-surface-area honeycomb design maximizes exhaust gas contact with the catalyst media, promoting thorough conversion of combustion byproducts for cleaner exhaust output.
  • Ribbed Converter Body — OEM-style ribbing minimizes thermal expansion and distortion as the converter heats up, maintaining structural integrity over the life of the part.
  • Seam-Welded Construction — Seam welds close to the converter body create a strong, tight bond that prevents catalyst movement and ensures a secure, leak-free assembly.
  • Integrated OEM-Style O2 Sensor Ports — Select units feature pre-installed oxygen sensor ports to simplify installation and restore proper sensor function.
  • EPA and CARB Compliance Options — The product line includes both Federal/EPA-compliant and California Air Resources Board (CARB)-compliant converters, with select units also approved for Colorado and other CARB-regulated states.
  • Weld-On Universal Design — Flexible fitment approach allows professional fabricators and experienced installers to adapt converters across a wide variety of exhaust configurations, custom builds, and project vehicles.
  • Broadest Body Configuration Selection — MagnaFlow offers more catalytic converter body shapes and configurations than any other manufacturer, supporting a broad range of exhaust layouts and repair scenarios.

Trusted by professional exhaust shops and performance enthusiasts alike, MagnaFlow is an American company with a proven track record in exhaust and emissions technology. These universal catalytic converters are an ideal solution for emissions system repairs, custom exhaust builds, or applications where a direct-fit replacement is not available or required. Professional installation is strongly recommended, as fitting typically requires cutting, welding, and exhaust fabrication. Always verify local and state emissions regulations before purchasing to ensure the correct compliance grade is selected for your area.
