catless x-pipe throwing cell, how to fix?
I just installed longtube headers and a catless x-pipe, and now I am getting four engine codes for catalyst inefficiency or something close to that. I am wondering, are there any mil eliminators or cell fixes I can use to clear this? Or what do people do to get rid of the codes?
thanks

I assume you are getting the codes because you don't have rear O2's or have them installed without cats. Anyhow, the rear O2's will throw a code if it appears that cats are not performing their job. Obviously, with no cats they aren't working well at all 
You need to install sims or have the rear O2s edited out to get rid of the codes. Between the two, edit seems to be more reliable than sims.
You probably should provide more detail on your setup and the exact codes being thrown.
