i was on the slp website and noticed the 2000 model year headers are all by themselfs. whats the difference between 1998-1999 and 2001-2002 headers? thanks for any help. by the way i already have hooker headers i just didn't realize there was a diffenece between model years.

 

The position of the emissions hookups is unique on the 2000s. 01s and 02s don't have EGR, and the hookups are different for the 98s and 99s. A race header will fit any year, though.
