    exhaust question, whats the diff?

    I have a quick question...Ive been looking around at headers and y pipes and noticed that on some sites it says 98-99 and 00-02, then others just say 98-02...What is the difference in the years and will headers and a y for an 01 fit a 98? Thanks, Scott.

    for your first question the difference is 98-99 have AIR and EGR fittings for emissions, 00-02 only have AIR fitting and 98-02 have no emissions hookups at all for race use only. Since you have a 98 then you need the 98-99 style header to pass emissions inspection. for your second ? yes they will fit but you will not have an EGR hookup
