Gone but not forgotten
thanks Jeff for the info! i'll check into that catback. EGR crap is next and gut the air pump. still got some odds and ends to finish up before i go back to the dyno. i want to do the MAT relocation and a crank pulley then maybe your chip before the dyno.-=Jeff=- said:Well the LT1 is very close to dual. the resonaotr is dual in/out. Liek I said, I have a Borla challenge system 2-3/4" dual pipes. I have NO AIR or EGR. When I removed the AIR/EGR stuff, I drove without changing the PROM and never got any codes. But even with the LT1 catback, you could leave all that stuff connected.
