That's the setup soon to be on my rig....the thing is, I have no clue what to go for as a high flow cat. I want something decent and not anything cheap and worthless. I'm goin all out this time around (I went cheap with my old ride and just got a muffler :crazy: ) Also, I've heard out here in California, that it's illegal to replace your cats if they aren't damaged. Is this true? Any way I can get around it? Or would anyone be able to tell or find out if I replaced ones that are functioning normally??
