Magnaflow 05-06 Terraza V6 3.5 OEM Underbody Direct Fit Converter

If your 2005 or 2006 Buick Terraza with the 3.5L V6 is showing a check engine light related to emissions, it's likely time to replace the catalytic converter. This direct-fit converter from Magnaflow is built to meet Federal EPA emissions standards, ensuring your vehicle remains compliant and the check engine light stays off. It's designed to replicate the original equipment's performance and fit, making the replacement process straightforward.

Magnaflow constructs this converter using strong 16-gauge 409 stainless steel tubing for excellent resistance to corrosion and a long service life. The spun body design, similar to the original part, features a single laser fusion weld to significantly reduce the chance of exhaust leaks. Its compact, low-mass construction also contributes to better thermal efficiency. The tubing is mandrel-bent to maintain the original design and geometry, ensuring it flows like the factory unit and helps preserve your vehicle's performance and fuel economy. Magnaflow uses advanced 3D scanning during their research and development to ensure a precise fit, so you can be confident it will function correctly.

This converter comes with the necessary gaskets and a Torca clamp, so you have the essential hardware to complete the installation without needing to cut or weld. Just be aware that this converter is not CARB approved and cannot be shipped to California. It's designed for vehicles registered in Federal/EPA emission states.
