Magnaflow 19-21 Nissan Altima 2.5L Single Underbody Direct Fit Converter

When your Altima's check engine light comes on, and you suspect the catalytic converter is the culprit, Magnaflow has a direct-fit replacement that's built to last. This converter is specifically made for the 2019 through 2021 Nissan Altima with the 2.5L engine. It's designed to meet or exceed Federal emissions requirements, ensuring your vehicle stays compliant with EPA standards for OBDII Federally registered vehicles.

You get everything you need for a straightforward installation right in the box: the converter itself, four bolts, two flange gaskets, four washers, and four nuts. Magnaflow uses highly corrosion-resistant stainless steel tubing, specifically 16-gauge 409 stainless steel for the main body, and durable 308 stainless steel for the MIG welds. The tubing is mandrel-bent to maintain factory flow dynamics, which helps keep your original performance and fuel efficiency. Magnaflow's research and development process uses 3D scanning to ensure this converter fits and functions just like the original equipment, replicating the OE spun body design with a single laser fusion weld to greatly reduce the chance of leaks. Its compact, low-mass design also helps with thermal efficiency.

This converter is designed for easy installation with no cutting or welding required, assuming you have the proper tools. It's important to note that this converter is not CARB approved and cannot be shipped to California. You'll be reusing the factory exhaust system components, but all the necessary gaskets and hardware for the converter connection are included, so you won't need to reuse corroded factory parts for the connection itself.
