I did to a search and got nothing. You basically repeated what I said. How does the EGR tube need to be modified? Bent, shortened? Ect... And removing the AIR and EGR is not an option by any means. Thanks!

you can modifiy the pipes or just buy the headers and !air/!egr.

98-99 headers Hey Fer,
Our 98-99 headers are inferior to the 00-02 headers. The 98,99 have the drivers side which is a log design and the passenger side is more of a Y type set up. The 00 headers have provissions for the EGR setup but you would have to use the 00 EGR tubes. Also you need the 00 Y pipe and cats from what i understand. I am considering upgrading my 98 manifolds to the 00 EGR set up. I think it would be a cheap upgrade as compared to a set of high dollar headers. I searched and have found many LS1s going in the high 11s and low 12s with stock 00-02 exhaust manifolds. It just seems that the 00-02s are always running 3-4/10s faster then the 98-99 cars, so it has to be in the intake and exhaust manifolds. I also searched to see how much difference in power can be had from upgrading from factory 00-02 manifolds and with stock heads and cam, i seen were cars only picked up an average of 12-14hp and tq. That gain to me is not worth 1000 bux. Sure a good set of LTs will help out with future internal upgrades but at this point having a fast low 12 sec street car is my goal.
