Product Details
Part No. 23457
Warranty Details (5 YR REPLACEMENT IF DEFECTIVE)
Keep the check engine light off with MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 23457. 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. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with Federal/EPA Emission systems.

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 EPA-compliant catalytic converters, providing assurance of genuine compliance while delivering quality that will last.

excellent product/fit
Submitted 12 years ago
It comes with all gaskets needed to replace it. It fits up with no issues. The trick to getting off the manifold nuts is to heat them up cherry red and use an impact wrench, no problems after that. I would recommend buying a new nuts though.
not what I expected
Submitted 13 years ago
A HUNK OF SLAG [*] UP THE O2 SENSER SO I HAVE TO BUY A NEW ONE AND BUY A GRINDING CONE TO CLEAR IT OUT. POOR MANUFACTURING!
Bottom Line No, I would not recommend to a friend
Seems good but time will tell i guess
Staff Reviewer - Submitted 13 years ago
The only issue i had was it has 4 02 sensor ports and my 98 has 3 o2 sensors so you will need an 18mm plug/bolt but other than that it seems well made with good clean welds it is brand new as I write this so we'll see how it holds up to the harsh winters here in the north east.
Bottom Line Yes, I would recommend to a friend
I was very satisfied with this product
