running like crap
I just got my car back from the shop i had them install hooker long tube headers and a magnaflow cat backexhaust on my 97 z28 camaro they took the cats off and the o2 sensors in them my car lacks power, runs like ****, and smells alot richer could it be because of the o2 sensors are nt on ne more ? Also i have a jet performance chip stage 2 and a k&n intake on it

Hopefully they did not away with the O2 sensors before the cat, otherwise tha car has no choice but to run crappy. The front O2s are needed by the PCM to compute the proper air/fuel mixture. The ones after the cat are only used to monitor the condition of the cats, and do not affect how the engine runs, but will light the check engine lamp if they are missing.

I'm a bit shocked that any legitimate shop would even remove them. It's a hefty federal fine if they or you get caught removing EPA equipment.
