C.A.R.B. Compliant

Bosal brings a wealth of OE experience to their aftermarket catalytic converters by utilizing many OE components and processes in their aftermarket manufacturing. That's the advantage to being an OE supplier. This synergy, along with massive loadings of precious metals to overcompensate for the high demands of high mileage vehicles, allows Bosal to create a superior catalytic converter versus the normal aftermarket product. This is why their converters have the reputation of solving the problem the first time.
