Will my truck still pass inspection if I put different muffler on it like past the dpf. And is there any recommendations on what to use. I was looking for more sound. Does bigger pipe make a difference. Or is it just gonna be quiet as long a dpf on there. Also Will it make a difference if I swap out the active air box with after market cai. Thanks

Kind of depends where you live as to the individual state regulations. The Feds say any modification is illegal .
