So what makes this converter better than the other products out there?
100% of Eastern Catalytic’s research and development efforts go into making the finest aftermarket and original equipment catalytic converters on the market. All of their converter wash coats come from the largest manufacturer in the world, ensuring maximum performance and the highest conversion of vehicle emissions of any catalytic converters available. Their proprietary NANO technology chemistry yields highly efficient loadings for lower cost and better converter efficiency. All of Eastern Catalytic’s converters are three-way converters (Palladium, Platinum, and Rhodium).
I live in California or New York, will this converter work on my car?
No. Within the states of California and New York, special emission laws have been put into effect that require that only CARB certified converters can be used as replacements on vehicles that are registered in those states. 

This item comes with a 5 year/50,000 mile manufacturer warranty.
