I want to remove the rear cat's from my truck but want to hear from the Cali guys that have done this. Has anyone removed the rear cat's and passed smog? I just want to know prior to going to a muffler shop if I should have the pipes made with a flange so I can put the cat's back on for smog or not. Thanks in advance. Also, if anyone is bored and wants to post mods they have done and still passed smog I would appreciate it.
