If I keep my car next year I'll be doing this an asking Powerflow, i want it so I can put it all back to stock afterwards.. got them to do a smiliar thing from the cat to the back box :)
So Stav is your system just straight through all the way now, did powerflow go from the manifold to the cat? Then take out the cat etc?
Hi, if you take out the 2 pre-cats what do you do with the lamda probes that are in front and behind the pre-cats? I'm thinking of taking off my pre-cats and want to know whats involved. I have a IS300 by the way! :)
