Product Information

Product Details
Part No. 4451219
Warranty Details (5 YR REPLACEMENT IF DEFECTIVE)
Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451219. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2003 Hummer H2. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Product Features:
  • Expertly crafted to replicate OEM-like flow dynamics, maintaining factory performance and fuel efficiency.
  • Simplifies installation with essential gaskets and hardware being included in the box.
  • Your trusted source for CARB-compliant catalytic converters, providing assurance of genuine compliance while delivering quality that will last.
