Product Details

Starting with the 308 stainless steel MIG welds, this MagnaFlow catalytic converter is built to last. The 16-gauge 409 stainless steel tubing offers strong corrosion resistance, which is crucial for a part exposed to road grime and weather. This converter is designed as a direct-fit replacement, meaning it bolts right up to your 2004-2007 Toyota Highlander, 2004-2006 Lexus ES330, 2004-2006 Lexus RX330, or 2004-2006 Toyota Sienna without needing any cutting or welding. MagnaFlow uses advanced 3D scanning during their research and development to ensure the fit and function are just like the original equipment.

The spun body design replicates the OE style, and a single laser fusion weld helps prevent leaks. This compact, low-mass design also contributes to better thermal efficiency. You'll get all the necessary gaskets and hardware included, so you won't have to reuse old, corroded factory parts. This converter is built to meet or exceed Federal emissions requirements for OBDII vehicles, helping you pass emissions tests and keep that check engine light off.
