1 bung 2 many ?
Hey everyone ! im not sure when my car is up for e-test but im pretty sure ill have to get it done by the end of the month to get my new plate sticker ! anyway, my question is, does the TXS RFL-TI exhaust pass e-test with the Highflow cat only ? (yes i do have a catless uppipe as well)
also, i was helpin a friend put the SAME setup on his WRX and noticed 2 bungs welded on his exhaust, one on the DP which i put the O2 sensor in, and another on the highflow cat ... A plug came with the system, but it only fits the DP bung, and the O2 sensor doesnt fit on in the HFcat bung, so i just left it open .... whats that bung for ? and what size do you know so i can put a plug in it ?
