Ls1 Headers???

[NJSPEEDER]

What is the difference between 98-99 headers and the 00-02 headers? Is it just the lack of EGR or is there more to it?

EGR & AIR

I think the 98-99 had the AIR fitting 90 degrees different from 00-02 and 01-02 obviously did not have EGR. I had to get the 98-99 style AIR pipes to bolt up to the used headers I bought.

The fittings are different as mentioned, as well as EGR, thats about it.

race headers solve those problems

98-2000 had EGR in same place. 2000 had AIR in different spot (same as 01-02). 01-02 had only AIR. I am pretty sure that is how it goes...

Race headers solve those problems :)
