Description

The Walker Exhaust 16566 Ultra EPA Direct Fit Catalytic Converter with Integrated Exhaust Manifold is specifically designed for 2004-2009 Mazda 3 models that are OBDII compliant (1996 and newer vehicles). This direct-fit catalytic converter features a bolt-on, OE-style design with integrated manifold assemblies that connect directly to the engine cylinder head and are compatible with all downstream connections. It incorporates a high-technology wash coat and optimized precious metal loading to effectively reduce tailpipe emissions and prevent "Check Engine" light illumination caused by emissions-related codes. Crafted from durable stainless steel, it boasts thick, OE-style flanges and manifolds for superior strength and longevity. Where originally equipped, it also includes aluminized heat shields to protect undercarriage components from heat. This product is backed by Walker's 25,000-mile/40,000-kilometer emissions warranty and a 5-year/80,000-kilometer structural integrity limited warranty. Please note that this catalytic converter is not legal for sale or use in California, Colorado, and New York, and is only legal in Maine for EPA Federal Emission Equipped Vehicles. It is advisable to consult your state's aftermarket converter regulations for specific legal requirements.
