Review on Direct Fit CalCat Carb 82664 Catalytic Converter by Walker Exhaust by Kelvin Ward

Perfect fit for my Cal car as listed in CARB pdf/app for brand model (2003 Toyota Matrix). Requires welding like most. Paid $80 for installation. Arrived as promised but left at the door without a signature so make sure the delivery area is secure. Have driven the car over 300 miles and over a week since the engine code was reset with no code returned. Best value for money I've found for California. Surcharge for prior checking of the Smog B4 installation and lambda calculation so that there are no further problems with the guarantee. Make sure it is your Cat B4 purchase confirmation code, reset it and make sure it comes back. Would give it a 5 but haven't ridden it many miles yet. The code should now have worked through b4 if it returned.
