Amazon's Vehicle Fit Tool (located at the top of the listing on desktop, below the pictures on mobile) should be used to confirm that the parts are suitable for your vehicle application. Purchased packages can only be returned as a complete package, as partial package returns are not allowed.

Due to increased emissions standards, this item is not certified for sale in California, New York, and Maine. If your vehicle is registered in these states, please do not purchase this item. However, if your vehicle meets California requirements but is not registered in these states, this product will be compatible.

Any modification of any kind will void all coverage for this item. The coverage will also be void if the catalytic converter substrate melts or breaks, as this is due to a problem with the car itself and not the catalytic converter.

Cosmetic defects may occur during the stocking and shipping process due to the size and shape of the product. The powder coat finish is designed to add life by minimizing surface scratches that can deteriorate over time due to the temperatures reached once in use.

Products damaged as a result of care, misuse, improper repair, improper installation, alteration, or modification will not be covered by the coverage. Additionally, the 02 sensors must be replaced when you replace the converter, or the coverage will be void. Replacing the front O2 sensor (the front wideband sensor), also known as the air-fuel ratio sensor or the downstream sensor, can help prevent a false P0420 code.

All AutoShack parts come with a six-month coverage. However, no reimbursements will be given for the delay, labor, mileage, or any other costs involved in the installation or re-installation of the auto parts in question.

AutoShack has been providing customers with replacement auto parts that meet their needs for both quality and affordability for over 40 years. The company also takes pride in delivering exceptional after-sales service.

AutoShack Catalytic Converters are built for long life expectancy on your vehicle. These converters are constructed from premium quality materials and are rigorously tested to meet or exceed your expectations. They are designed to protect against warping or cracking, ensuring maximum flow to increase the power and performance of your engine.

The catalytic converters are made from premium quality materials, including precious metals and large substrates, which minimize pollutants in your exhaust. They have also been tested under extreme conditions for heat resistance and are quality-inspected to meet OEM specifications.

AutoShack's catalytic converters are ISO / IATF 16949 certified, ensuring a direct fit and high-quality materials that meet OEM specifications. The company offers a large selection of catalytic converters for a wide variety of makes and models.

Your catalytic converter is an essential exhaust emission control device that reduces toxic gases and pollutants from your vehicle's exhaust. Common symptoms of a failing catalytic converter include sluggish engine performance, acceleration, darker-than-normal smoke from the exhaust, and a change in the smell of the exhaust, perhaps smelling more of sulfur or rotten egg.

This direct-fit, 100% new, EPA-compliant catalytic converter is a replacement for 2004-2006 Toyota Sienna, 2004-2007 Highlander, and 2004-2006 Lexus RX330 3.3L V6 AWD and FWD models. Professional installation is highly recommended.
