It can take a while for the PCM to throw a code for the rear O2s so you might have to run those plug defoulers for quite a long time and still end up setting a code eventually.

or you could just get them deleted(as mentoned^^) when you get a tune, but i see why Mangled has them.. if i dont get a tune before i get some long tubes i will do this mod... better than getting long tubes, with the cats still in and no delete, just do this mod so you dont have the rework the exhaust again to cut them out,.. unless some people like running them?

THE REARS are self heated units so they dont need to be in the stream to work
I think this would work
makes since to me
Id just like to know a way to get the fronts to stop throwing p1133 and p1153 after a LT install on my corvette
noone at the corvette forum knows a way other than to get them tuned out
maybe you guys know a way

On my 95 I have true duels with one O2 sensor, reading one bank. Sinse i dont have a y or an h pipe to put the O2 sensor in it is running really rich. If i do this trick will it make it run better.

Ok, dumb question probably but I'm askin it anyway. You said you can get the computer tuned once you remove the Cats and o2 sensors right? Do you have to take it somewhere or are you talking about a programmer from like Hypertech or JET? I use to have a Hypertech tuner and I don't remember there being an option for that. Yeah, dumb question, I know, but if you don't ask you're still in the dark...........

Some of us go to performance shops where a more experienced person might "tune" our vehicles....
