    Header question

    I was looking in buying some pacesetter Lt and pacesetter ory and i wanted some info on the air & egr valve. Since im gonna remove the cats its pretty pointless to keep them right? I know one says emission legal and one is race only, but its only emission legal if your going to add cats right? So i should probably just buy the race ones, and just have a dyno shop remove the codes correct?

    ya if you are not worried about emissions do that you will not gain any power but you will have a cleaner look.

    I don't think longtubes are legal whether you have cats or not. It's not really gonna matter if you keep the air and egr or not.

    Correct on you have to have cats for emissions, your air fittings are to help for emissions. also, if you are going to remove the cats, don't get air fitting headers... And, yes the dyno shop can delete your egr codes so you will not throw codes... Go with race ones!
