Product Details

The Magnaflow 4451356 is a universal catalytic converter designed for custom exhaust applications requiring a 2.50-inch inlet and outlet diameter. This California-grade catalytic converter meets stringent CARB emissions standards, making it legal for use in all 50 states including California.

Key Features:

  • 2.50-inch inlet and outlet diameter for universal fitment
  • California CARB compliant (CARB EO approved)
  • Stainless steel construction for durability and corrosion resistance
  • High-flow design minimizes backpressure while meeting emissions requirements
  • OBD-II compatible with oxygen sensor ports
  • Direct-fit replacement for welded exhaust installations

Magnaflow catalytic converters feature precision-wound substrate technology that maximizes surface area for optimal catalytic conversion efficiency. The stainless steel body and heat shield provide long-lasting performance in demanding exhaust environments.

good price, Wrong part will not work on my car . RMA process way to slow , If amazon or any other mail order company was this slow at there RMA process they would be out of business . Needing this part for mechanic show had to spend more money to get one else where because I can not wait a round for your slow process for returns customer service would suck . So now I out the money for the part and time of service because I can't pass your slow response on to my customers. Will not buy from you ever again price means nothing when it put customers out this long.

Thank you
