I put a straight throught exaust on my 1999 Z28 camaro and now the check engine light wont go off because of the cats are not there. I was wondering if there is anything i can do to get it to someone told me to get resisters. But i dont know what kind to get. Please help.

 

What you need is O2 sims or have them deleted via tune.

 

couldnt u keep the o2 sensors buy welding in a bung for them in the pipes

 

Won't matter, without cats you'll still get the same SES light.

Click the alphabetical sponsors list in the upper right hand corner and enter your zip code. If a sponsor's shop is close to you, you can probably get them deleted with a basic tune relativley cheap. ($150 or less). You could also post in your regional forum and ask for somebody with software that can delete it for you. Or you can order O2 sims, they are around $90/pair. I don't like them, they seem to go out a little too often. I had two different ones fail on me in just over a year.
