98-99 vs. 00-02 Headers?
you'll have to change out the EGR pipe going to the passenger side header and get a newer 00-02 y pipe If your talking about switching stock manifolds. If your talking about longtubes, then they should work but you will still need to change the EGR tube if you plan to keep it.
i got LT's with out egr you just need computer delete egr and blockoff egr on intake manifold. i purchased a slp vette ls6 intake without egr. ps my jethot lts came with y pipe and cats however the cats fit inside the y pipe and would NOT pass a visual inspection (not what i wanted).
