MagnaFlow Conv DF 90-93 Q45 4.5L Lf

If your check engine light is on and you suspect a failing catalytic converter on your 1990-1993 Infiniti Q45, this direct-fit unit from Magnaflow is a solid option. It's designed to meet Federal emissions requirements, helping you pass inspection and keep your Q45 running smoothly. Because it's a direct-fit converter, installation is straightforward, with no cutting or welding needed, making it a job you can often tackle yourself with the right tools.

Magnaflow builds this converter with 16-gauge 409 stainless steel tubing, which offers good resistance to corrosion and helps ensure a long service life. The internal design uses mandrel-bent tubing to maintain consistent exhaust flow, and the single laser fusion weld is intended to reduce the chance of leaks. They use 3D scanning during development to ensure the shape and fit match the original equipment, so it should integrate seamlessly into your exhaust system.

This converter is designed for vehicles with Federal/EPA emissions systems. It's important to note that this converter is not CARB approved and cannot be shipped to California. Make sure to check your vehicle's specific emissions system requirements before purchasing.
