to all who are running exhaust/headers with no cats converter are you having any problems because I plan on running the O2 sensors but with no cats.

Why would you have any problems with the O2s? Most guys around here run no cats, it will not effect the O2s in any way.

You dont need the rear O2's to run but regardless cat or no cat you neeed the front O2's unless you are running a carb then WGAFRA...because I plan on running the O2 sensors but with no cats.

I'm running headers, no cats and not a problem one. But then again, I don't have rear O2s, only front in the headers.
Long tubes, front O2s, no CATS, no problems. Have the rear O2s programmed out of the PCM, or buy O2 simulators for a quick fix. Ide still get it programmed out at some point though.
