Ok...I have the Hotshot header on order but now there's all this stuff about the catalytic convertor is built into the stock exhaust manifold. Is this true? Does anyone know if there are 2 cats on the B15's, like one in the manifold and one right before the exhaust? I have to pass smog every year to get my inspection sticker and if I don't have a cat, then I probably won't pass. Can anyone shed any light on this subject?
