Im sure this question as been asked sine the dawn of time but im gonna give it a swing anyway. im new to the titan community but im loving my truck so far. My check engine light came on and after having it tested it i was told it was the cat's bank 1 and bank 2. I have a friend who has an armada that he bought pacesetter headers with built on cat's but did not ever use them due to him selling his truck after a wreck. He's willing to let them go as a set for $300 which is good but will this resolve my check engine light issue and allow me to pass the emission test. (Atlanta Ga residence)
