MagnaFlow Conv DF California Grade 90-91 GM Lumina APV/Silhouette/Trans Sport 3.1L

If you're working on a 1990 or 1991 Chevrolet Lumina APV, Oldsmobile Silhouette, or Pontiac Trans Sport with the 3.1L engine, this Magnaflow California Grade Direct-Fit Catalytic Converter is what you need to keep your emissions system in check. This converter is specifically designed to meet the stringent requirements of the California Air Resources Board (CARB), ensuring it's legal for use in California and other states with similar emissions regulations. It's built to function just like the original equipment, helping to prevent that dreaded check engine light from coming on.

Magnaflow puts a lot of thought into how these converters are made. They use advanced 3D scanning during their research and development to make sure the fit and function are spot on, just like the factory part. The tubing is mandrel-bent for better flow, and the whole unit is constructed from highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel for the tubing and 308 stainless steel for the welds. This means it's built to last and resist rust, even in tough conditions. The spun body design, with a single laser fusion weld, is a smart way to reduce the chance of leaks, and its compact, low-mass design helps with thermal efficiency.

What's really great about this converter is that it's a direct-fit part. That means no cutting or welding is needed for installation, making it a much simpler job for you. Magnaflow even includes the necessary gaskets and hardware in the box to help make the installation process smoother. This is a well-built replacement that's designed to meet or even exceed CARB requirements, giving you peace of mind that your vehicle is running clean and legally.
