Product Details

The single laser fusion weld on this MagnaFlow catalytic converter is designed to greatly reduce the possibility of exhaust leaks. This is a key detail because a leak here can affect emissions readings and potentially trigger your check engine light. It's constructed with high-strength 16-gauge 409 stainless steel tubing, which is known for its excellent corrosion resistance, meaning it should hold up well over time, even in areas where road salt is used.

MagnaFlow uses advanced 3D scanning during their research and development to ensure this converter fits just like the original equipment. The tubing is mandrel-bent to maintain the factory design and geometry, and the compact, low-mass design helps with thermal efficiency. This direct-fit converter is designed to meet or exceed Federal emissions requirements for OBDII vehicles registered in states with Federal/EPA emission systems, helping you pass emissions tests. It also interchanges with the original equipment part number 18450-50350.

Installation is made simpler because this converter is designed as a direct-fit, meaning no cutting or welding is required. You'll also find the essential gaskets included in the box to help ensure a proper seal. Please note that this converter is not CARB approved and cannot be shipped to California.
