Our take on the MagnaFlow Catalytic Converter 16420

The MagnaFlow 16420 is a direct-fit, dual-inlet/dual-outlet three-way catalytic converter for Chrysler and Dodge vehicles. It uses a ceramic substrate in 409 stainless steel with 16-gauge tubing, and it carries Federal/EPA compliance rather than California CARB approval. It suits owners of older Chrysler and Dodge models doing an OE-style replacement who want a bolt-on fit and a sturdier body than generic universal units. Reviewers rate it around 3.7 out of 5: fit and build quality draw praise, while some report fitment trouble and short service life.

Best forOwners replacing a failed factory converter on Chrysler or Dodge vehiclesDrivers in states that follow Federal/EPA emissions rulesDo-it-yourself installs that want a bolt-on, clamp-on fitBuyers who prefer stainless steel over aluminized mild steel
Pros
  • 409 stainless steel body and 16-gauge tubing resist corrosion better than mild steel
  • Direct-fit dual-inlet, dual-outlet design with factory-style mounting
  • Three-way ceramic catalyst with oxygen sensor ports included
  • Federal/EPA compliant for emissions testing in most states
  • Heavier 28 lb build than many universal converters
Cons
  • Not California CARB approved, so it cannot be sold or used there
  • Some owners report fitment issues on certain model years
  • A few reviewers report early failures or check-engine lights returning
  • Dual-inlet layout limits it to specific Chrysler and Dodge applications

Questions and answers

Is this converter legal in California?
No. It is Federal/EPA compliant only, not CARB approved, so it cannot be sold or installed in California or other CARB states.
Will it fit my Chrysler 300?
It is listed for Chrysler and Dodge applications, but fitment varies by year and engine. Confirm your exact model year and engine against MagnaFlow's application chart before buying.
Does it come with gaskets and hardware?
It uses bolt-on inlet and clamp-on outlet mounting. Check the listing for included gaskets and clamps, since some buyers report needing extra hardware.
Will it fix a P0420 code?
If the code comes from a failed converter, owners report it clearing after install. If the code has another cause, such as a bad sensor, it will not help.
How does it compare with a universal converter?
It is a direct-fit unit with factory-style flanges and dual inlets, so it installs faster than a universal weld-in converter, though it fits fewer vehicles.
Is the substrate ceramic or metallic?
It uses a ceramic three-way substrate, which is the common OE-style choice for durability and cost.
