So I would like to go with the Fabspeed bypass pipes and i'm not too sure on headers yet I saw these but b/c they are so cheap I am not sure if they are any good

Do you plan on removing all 4 cats or just the secondary, depending on your car you may only have 2 cats.

If you are only removing the secondary set you should be fine if you are removing all of the cats I believe you will have cel issues.
