Is it ok to run catless H-Pipe without CEL eliminators?

Quick question, I just installed a MAC offroad catless H-Pipe. I ordered the CEL eliminators but received two identical ones, and the connectors on the O2 sensors are different from right to left. Will my car run poorly without the CEL eliminators? Thanks!!

The MIL eliminators are just O2 sensor foolers. They're used to trick the computer into thinking that the car has cats. You should be fine until you sort that issue out. You will most likely get a Check engine light though. [MENTION=18798]96_GT[/MENTION]

Yeah, I figured it out. I had to modify one of the MIL Eliminators to fit the socket properly. Installed them and cleared my check engine light.

Just an FYI, taking the cats off of the car will not make the car run poorly. The only codes you should ever really get should be a P0420 and P0430 for catalyst deficiency. If you get others, there may be a different issue.

Also for those MIL elims, they do not always work. But they do a good majority of the time. so hopefully your CEL stays off.
