Magnaflow Conv DF 03-04 M45 V8 4.5 OE Mani

Magnaflow is well-known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is a prime example, designed to keep your 2003-2006 INFINITI Q45 or 2003-2004 INFINITI M45 running smoothly and without check engine lights. It's built to meet Federal emissions requirements, so you can be confident it's compliant for OBDII Federally registered vehicles.

What sets this converter apart is its construction. It uses highly corrosion-resistant stainless steel tubing, specifically 16-gauge 409 stainless steel, which means it's built to handle the elements and last for many years. The spun body design replicates the original equipment, and a single laser fusion weld is used to greatly reduce the chance of exhaust leaks. This compact, low-mass design also helps with thermal efficiency. Magnaflow uses 3D scanning during their research and development to ensure this part fits just like the original, making installation straightforward. Since it's a direct-fit part, you won't need to cut or weld anything; just use the included gaskets and proper tools for a clean installation.

This converter is designed to meet or exceed EPA emissions standards. It's important to note that this part is not CARB approved and cannot be shipped to California. You'll receive the necessary gaskets to ensure a proper seal when you install it.
