The '93 -'97 headers have the tubes for the air pump...do they also have the EGR connection? Mine isn't a California emissions vehicle but of course it has an EGR valve.

All 460’s with speed density fuel injection have 1 o2 sensor upstream of the cat. 96-97 California 460’s are mass air flow , they have a left o2 sensor and a right o2 sensor up stream. Im not sure if they have a 3rd o2 sensor downstream.
Speed Density fuel injection is not affected by removing the cat other than a performance increase and less exhaust heat.
The 96-97 Banks California headers Y pipe has a Left & Right o2 bungs, these will need to be plugged and another bung welded on the Y pipe after the 2 pipes come together .
