if you don't have tuning or an 02 sim you will most likely get a check engine light, having a cel will cause you to fail and emissions test. But with an 02 sim and the stock secondary cats in the exhaust you should pass emission testing just fine. You should really get tuning to maximize the benefit of the dp's.
