Review on 🚗 Walker Exhaust CalCat Carb 82555 Catalytic Converter - Optimized with Integrated Exhaust Manifold for Enhanced Performance by Alex Taylor

The bolting to the head was fine, but the outlet flange was not in the same plane as the pipe flange, resulting in the catalytic converter and pipe being pinched when tightening the nuts. None of the heat shield attachment points were in the right places. I spent almost two hours modifying the shields to fit. It's definitely not a direct replacement. I have been an automotive technician for over forty years and have used Walker parts with no problem, but unfortunately I have lost confidence in their products.
