"If you don't have cats then I wouldn't worry about the smog pump stuff.. Even with it all hooked up and no cats it ain't gonna do much, if anything at all. If you really wanted to hook it up the right way you would need to buy a whole new h pipe with the cats installed. Then you can hook it up back to stock." Right, the original idea was 100% stock. Now we have a "legal" dilemma. It is illegal to tag it in its current state. While this is no big deal to most I differ on this point. The titled owner and I are working out a solution. We are leaning toward splitting the cost of replacement parts if i can find them cheap enough, otherwise back it goes and I look for another one.
