The Walker CalCat line focuses on CARB-compliant manifold catalytic converters for both OBDII and non-OBD vehicles, making it a strong match for regulated repair needs where exact fit and certification matter. This part cross-references MagnaFlow Exhaust Products 5481342 for the same application.

Common Repair Uses

• Replacing a failed front left catalytic converter/manifold assembly
• Addressing emissions test failures on CARB-regulated vehicles
• Restoring exhaust flow after catalyst efficiency deterioration
• Correcting exhaust leaks at the manifold or flange connection
• Replacing a rusted or damaged OE-style exhaust manifold converter

Installation Notes

Verify the front left position and vehicle year before ordering. This application uses a 6-bolt welded flange inlet and a 3-bolt welded flange outlet, so the existing exhaust connection points must match the vehicle configuration. Mounting hardware is not included. Confirm sensor and flange alignment during installation to ensure proper sealing and fit.

Quality Assurance

Walker designs, tests, and validates CalCat manifold catalytic converters to meet CARB standards and deliver OE-style fitment. Part number 83682 is certified for California and New York emissions requirements, supporting compliance-focused repairs on the listed Toyota applications.
