Product Details

The MagnaFlow 5551520 is a California Grade, CARB Compliant direct-fit catalytic converter engineered as a precise OEM replacement. Designed with a spun body construction and joined by a single laser fusion weld, this converter replicates the original equipment design to minimize the risk of exhaust leaks while maximizing thermal efficiency through its compact, low-mass profile.

Key Features:

  • CARB Certified: Meets or exceeds California Air Resources Board (CARB) requirements — legal for use in California and all other CARB-restricted states
  • Free-Flowing Mandrel-Bent Tubing: Eliminates flow restrictions to maintain OEM-level exhaust performance and fuel efficiency
  • 409 Stainless Steel Construction: High-strength, corrosion-resistant stainless steel tubing and body for long-term durability
  • OEM Spun Body Design: Replicates factory geometry for a confident, leak-resistant fit
  • Single Laser Fusion Weld: Precision welding greatly reduces the possibility of exhaust leaks at the body seam
  • 3D Scan-Verified Fitment: MagnaFlow's metrology department uses advanced 3D scanning during R&D to ensure form, fit, and function match the original equipment
  • No Cutting or Welding Required: Bolt-on direct-fit installation using standard hand tools; gaskets and hardware included
  • Ceramic Substrate: Delivers reliable emissions reduction and helps keep the check engine light off

This catalytic converter has undergone rigorous testing to comply with CARB guidelines, making it a street-legal replacement for vehicles registered in California and other emissions-restricted states. The included installation hardware simplifies the job, making it a straightforward DIY replacement.

Haven't found the time to work on my SL.

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.

Look forward in working with your team more in the future.

I received exactly what I ordered and shipping was on time

Easy and fast! Thanks!

Great if I order again I will be using the same website again. Thanks

No problem with ordering and having the items ground shipped to a forwarding company (I am based in the UK)
