cat gone??
I just took a look under my 93 camaro and saw that the previous owner straight piped where the cat converter should be. So no converter. Will this affect theperformance very much? ??? .The car vibrates like crazy when idling. Doesa 1993 model go into a safe mode if this is removed?Its a 3.4 motor by the way. Been tuned up and all compression checks and fuel pressuresare ok.

RE: cat gone??
if your front o2's fail then I believe you run in open loop. But that will not be affected by the presence or absence of cats. now, are you calling open loop the same as safe mode? I guess I havent heard this before. when I think safe mode i think of the new fly by wire cars and their "limp home" mode. but still, the cats have temp sensors on them and thats it. the rear o2's will only throw a light if they are removed and nothing more.

Ok thanks about the o2 info . When i went under and checked my exhaust mounts i noticedthe whole systemwas pretty stiff all over. is this normal? I always thought they had some "play to them"
