Magnaflow 2011 Toyota Sienna 3.5L Direct Fit Converter

The 2011 Toyota Sienna 3.5L uses a specific catalytic converter to manage emissions, and this Magnaflow unit is built to meet those needs, especially in California and other CARB-restricted states. It's designed as a direct-fit replacement, meaning it bolts right up to your existing exhaust system without needing any cutting or welding, simplifying the installation process. This is crucial for ensuring your check engine light stays off and your vehicle runs cleanly.

Magnaflow constructs this converter using highly corrosion-resistant 409 stainless steel tubing, which is strong and built to last. The tubing is mandrel-bent to maintain smooth exhaust flow, helping your Sienna perform efficiently and maintain its factory fuel economy. They also use a compact, low-mass design that allows for better thermal efficiency. The single laser fusion weld is designed to reduce the chance of leaks, and the MIG welds on the durable 308 stainless steel further contribute to its solid construction.

When you get this converter, it comes with the necessary gaskets, including a flat ring gasket and a donut gasket, so you have what you need to get it installed properly. Magnaflow has put this converter through extra testing to ensure it meets California Air Resource Board (CARB) requirements, making it a legal and reliable choice for your Sienna.
