Product Information

Product Details
Part No. 4451457
Warranty Details (5 YR REPLACEMENT IF DEFECTIVE)
Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451457. 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 to fit the 1996-1999 Chevrolet C1500, 1996-1999 Chevrolet K1500, and additional vehicles. 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:
  • Torca AccuSeal Exhaust Clamps provide a full 360-degree equally distributed clamping force preventing pipe distortion while creating a complete seal and maintaining serviceability
  • Your trusted source for CARB-compliant catalytic converters, providing assurance of genuine compliance while delivering quality that will last
  • Mandrel bent tubing retains OEM-like design and geometry, ensuring smooth exhaust flow for peak fuel economy and engine operation
  • High strength 16 gauge 409 stainless steel tubing for exceptional corrosion resistance and maximum service life
