Product Details

Eastern Convertors uses advanced manufacturing methods, including automated workstations, spinner welding equipment, and high-speed production lines, to produce converters to exact OE dimensions.

Installation Notes

Confirm the vehicle is a 2015, 2016, or 2017 Honda Odyssey with the rear undercar configuration before ordering. This converter uses 3-bolt welded flange inlet and outlet connections and includes one O2 sensor port, so the existing exhaust layout and sensor placement should be matched to the part number 41253 application. Verify all flange surfaces, gaskets, and sensor threads during installation for proper sealing.

Not for sale or use in California, Colorado, Maine, or New York on vehicles with California emissions.
