Has anyone put an HP Racing Header on there car without the O2 Sim? I recently had the HP Racing Header installed and now my car is shaking. I was wondering if it could be because I have not installed the O2 sim yet. I thought that the sim only prevented the check engine light from coming on.

yes it is because you have no O2 sim....you need it for HP racing downpipe,
or you can get a bung adapder and weld it on the down pipe, plug in the O2 sensor and
have someone like hondata tweak the ECu untill it gives correct readings.

I used an old O2 sensor to plug the third hole. (That sounds really bad) I have the O2 sim from Wannabefast. Will that work if I get it installed?

Is it bad to leave the check engine light on if you know its from the O2 sensor? This was caused from a new high flow cat.

My light didn't even come on when I put on the new high flow cat. Hey cracker, did you have the HP Header too? You having any problems?

did u tap into the right wires?
also, did you reset the ecu?
double check the header to make sure every thing is tightened

I took it to a muffler shop to have it installed. I watched the guy do it. He just did a simple swap of the cats, nothing surgical done to the wires or anything like that. I had reset the ecu as soon as I brought it home from the muffler shop and the light didnt come on for the first time until 2 days later. I havent reset the ecu again since this happened.

Having the cel come on after putting these high flow cats onto our cars doesnt negatively affect our vtec switching on and off does it?

I'm concerned with wether or not the cel light caused by our O2 sensor is affecting us in peformance in any way at all actually.
