Product Details

Magnaflow is known for making exhaust components that flow well and last a long time. This direct-fit catalytic converter is built specifically for your 2003-2004 Cadillac CTS with the 3.2L engine, designed to keep your check engine light off and meet federal emissions standards.

This converter uses free-flowing, mandrel-bent tubing, which helps maintain factory performance and fuel efficiency. It's constructed from strong 16-gauge 409 stainless steel for excellent resistance to corrosion, ensuring it holds up over time. Magnaflow uses advanced 3D scanning to make sure this part fits just like the original equipment. The design replicates the OE spun body, and a single laser fusion weld is used to greatly reduce the chance of leaks. Its compact, low-mass design also helps with thermal efficiency.

Installation is made easier because this converter is a direct fit, meaning no cutting or welding is required. It comes with the necessary gaskets and hardware, so you won't have to reuse old, corroded parts. This converter meets federal emissions requirements for OBDII vehicles registered in states that follow federal or EPA emission standards. Please note, this part is not CARB approved and cannot be shipped to California.
