I got my racing beat 3 " downpipe and was gonna put it on, but got to thinking, it already has one bung welded in it for the o2 sensor. But If i run a EGT and a A/F, I need 2 more dont i?
Originally posted by rx7passion i dont think so mike, the egt you need another hole but i believe you should be able to splice into the exsisiting o2 wires.
I was told that splicing the O2 signal wire was a no no ?
