    1 Top Rated Question

    2 part questions. 1. If installed will it pass smog in the state of California. 2. If it doesn't couldn't I just install the factory cats to pass smog

    • These headers will not pass a smog inspection in California since they are not CARB certified. Even if the factory cats are installed, they still will not pass.

      Sounds Amazing!!!

      So for this buy we bought the Catless x pipe, and boy did my ears rings after this. If you're going for a raspy loud sound this is all you! Great buy!
