i had 2 cut off before i got my o/r H. it was a little louder,and my CEL never came on. i've never heard the Hooker mufflers,but i've heard they are very good. try www.mustangexhaust.com

if your rear oxygen sensors are before the last set of cats the cel will not come on

the rear O2 sensors are after the 2nd pair of cats, however if u only remove 2 cats, the ce should not turn on. It will make it notably louder. if i were u, i would just swap out ur mid pipe with an after market one like bassani wich only comes with 2 cats. ur ce light will not turn on, and it will be much louder, because it somes with high flow cats

cut them all off

well it depends. do u have to pass emission where ur at?? an az we do, but now that i got an sct chip, my check engine light wont come on for no cats, so i go right through emissions!!! and now i got no cats!!

Do you have to get the SCT chip to get rid of the check engine light, or can I just use my SCT XCalibrator tuner to get rid of it? Otherwise I'm ordering MIL eliminators with 02 wire extenders.

Got my rear cats off and no CEL for at least a year

i have an sct chip so my tuner made it so that the ce light wont come on for no cats as measured my the o2 sensors. i think the handheld tuner can do it too, but not sure.

i believe you can just go to like autozone for the code
