Toyota Highlander Catalytic Converter - MagnaFlow - OEM Grade Direct-Fit (2001–2004). A direct-replacement catalytic converter engineered to match OEM fit and flow for 2001–2004 Toyota Highlander models, designed to restore proper emissions control and keep your vehicle operating within federal standards where applicable.
This MagnaFlow OEM-grade direct-fit converter replicates OE spun-body geometry and uses 3D-scanned development data to help ensure reliable fitment. The unit features a compact, low-mass design with a single laser fusion weld at the spun body to reduce leak risk. Constructed with high-strength 16-gauge 409 stainless steel tubing and durable 308 stainless welds, it resists corrosion and is built for long service life. Hardware and gaskets are included to simplify installation without cutting or welding when matching factory attachment points.
