Quick question.....
P.S you need oxygen sensors up front so your cars knows if it runing lean or rich. The rears you can remove with a o2 simulators, but you wont pass smog if you don't have them.
All LS1 Fbodies come with AIR fittings, only 98-00 come with EGR...
But definitely see if you can get the ones without AIR or EGR....The tune will take care of it...
