This feature is tested to improve air flow, horsepower, and torque. The interior components of the catalytic converter are made through the NANO technology chemistry that aims at improving gas loadings for better efficiency at lower cost. The aftermarket part also comes in 409 stainless steel, satin-finished body and high-performance steel mesh retainers to allow longer operating life. It is sold with new gaskets, mounting hardware, and oxygen sensors to better improve the exhaust system's performance. Eastern catalytic converter can work with an engine size of up to 8.0 L.
