Review on Walker 83185 CalCat Manifold Converter by Isaac Islam

This was one of two catalytic converters that fit my car, excluding the OEM. The part is very similar to the OEM part and I noticed an improvement in performance as soon as we tested the car. The difference in appearance between this part and my OEM part was the smaller heat shield, you cannot use the OEM shield as the bolt pattern is different and only one of the bottom brackets will fit as the width is slightly smaller and the bolt won' Treason. Finally, the packaging is minimal, resulting in the gasket being squeezed out during shipping. I hope this doesn't affect performance, but I was confused by the lack of packaging material in the box that shipped nationwide.
