What does 'direct-fit' mean for this catalytic converter?

Direct-fit means this catalytic converter is designed to bolt directly in place of your original equipment converter. No cutting, welding, or fabrication is required for installation, simplifying the process when you have the proper tools.

Is this catalytic converter legal in all states?

This MagnaFlow catalytic converter is EPA-compliant and meets Federal emissions requirements. However, it is not CARB approved and cannot be shipped to California due to stricter emissions standards in that state.

What materials is this catalytic converter made from?

The tubing is made from high-strength 16-gauge 409 stainless steel, which offers excellent resistance to corrosion. The welds are durable 308 stainless steel MIG welds.

Product Details

If your check engine light is on and you suspect an issue with your catalytic converter, replacing it with a direct-fit unit like the MagnaFlow 16421 is a solid plan. This converter is built to keep your 2005-2017 Chrysler 300, or compatible Dodge models, running cleanly and legally. It's designed to meet Federal emissions requirements, ensuring your vehicle passes EPA standards for OBDII Federally registered cars, whether they have California or Federal/EPA emission systems.

MagnaFlow uses high-strength 16-gauge 409 stainless steel for the tubing, which is known for resisting corrosion and lasting a long time. The mandrel-bent tubing maintains the original shape and flow characteristics, helping your engine perform as the factory intended and keeping your fuel efficiency steady. They've replicated the OE spun body design, and the single laser fusion weld significantly cuts down on the chance of exhaust leaks. This converter also features a compact, low-mass body for better thermal efficiency. Installation is made simpler because it's a direct-fit unit, meaning no cutting or welding is needed – just use the proper tools and follow the instructions.

This MagnaFlow converter comes with two O2 port plugs. While it meets Federal EPA standards, please note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for the best results.
