I have a 2007 2500 6.7 with a 6 speed Manuel. I purchased a H&S Xrt (way excited i got one before they cant make them) but my question is can i just hollow out the cat and DPF and put the exhaust back on so it looks stock but still get good results? Wyoming doesnt check but I am worried if I drive it to some states that may care. What do you guys think
