I will be installing the kooks mid headers on my G8 Gt have two questions really.
1) since I am installing the cats also will I trip the CEL for the rear O2 sensor. I cant seem to find a definite answer on this.
2) Will I need set of filtered extenders for the rear O2 sensors per the thread on https://www.g8board.com/forums/116-ex...ooks-mids.html
My guy got me rolling in under 2 hrs and he had to torch the rusty bolts on the cats to boot. I never did it myself and watched my mechanic do the whole process. It seemed pretty easy. Of course its easier to do it on a lift.
Good luck and happy modding!
