My buddy claims he saw stuff at Pep Boys that you put in your tank of gas right before inspection and it supposedy will allow you to beat the smog test. Being that I no longer have cats and am due for inspection in about 7 months does anyone know if this stuff really works? Of course if the inspection place does a visual I am out of luck unless they are ignorant and I can get away with saying the prochamber is actually a big high flow cat
