Well,,,,,,,,,, You have FOUR O2 sensors. Two Primary before the cats and two emission related after the cats.
If you remove the cats you WILL get DTCs due to the after the cat sensors. You have to have them tuned out to avoid DTCs
What do you expect to get by removing the CATs??? I hope it isnt GOBS of new found HP. The best you will see on a mostly stock engine is around 7-10 HP/
I hope it isnt a lot more noise, cause you wont see much.
