Product Details

The MagnaFlow 21-239 is an OEM Grade, Federal/EPA Compliant direct-fit catalytic converter engineered to restore proper emissions performance and keep the check engine light off. Built to replicate original equipment specifications, this spun body converter installs using standard hand tools — no cutting or welding required.

MagnaFlow's dedicated metrology department employs advanced 3D scanning technology during the research and development process, ensuring precise fitment that matches the original factory part in form, fit, and function. The single laser fusion weld on the spun body design minimizes leak points, while the compact, low-mass construction promotes greater thermal efficiency for optimal catalytic operation.

Key Features:

  • Free-flowing mandrel-bent tubing maintains OEM-like exhaust flow geometry for peak fuel economy and engine performance
  • High-strength 16-gauge 409 stainless steel tubing delivers exceptional corrosion resistance and long service life
  • OE-sized barbed exhaust hangers crafted from corrosion-resistant 410 stainless steel reduce noise and vibration
  • Spun body design with single laser fusion weld minimizes leak potential
  • Compact, low-mass design promotes greater thermal efficiency
  • Bolt-on direct-fit installation — no cutting, welding, or bending required
  • Includes gaskets and hardware to ensure a leak-free seal without reusing corroded factory components
  • Ceramic substrate engineered to meet specific vehicle emissions requirements
  • Designed to meet or exceed Federal EPA emissions standards for OBDII-equipped vehicles
  • Interchanges with OE part numbers 1570C326 and 1570C782

This converter is compliant with Federal/EPA emissions standards and is intended for use on federally registered OBDII vehicles. Not for sale or use in California, Colorado, or New York. MagnaFlow warrants this converter against manufacturer defects for 5 years and against emissions failure for 25,000 miles on vehicles registered outside of California.

I received my order of Shurflo replacement o-rings very quickly - sooner than expected. Unfortunately, I really only needed 1 or 2 o-rings, but they are only offered in a pack of 10. I'll never use 10 o-rings, so it was wasteful spending. I shopped other companies, and could not find packs of 1 or 2, and Boatplicity was the least expensive for what is available on-line.

Quick and easy!

Fast shipping

Easy to oreder - an excellent price.

Quick delivery and product is looking good but have not installed yet.

This was one of the few places I could find that had these in stock.

Price was higher than others but it was in stock and checkout was easy soni guess it's a wash
