My stock one has an 02 sensor at the cat and an 02 sensor bung towards the top pretty close to the turbo but it doesn't have a sensor in it. When I go to purchase a catless dp does it need to have 2 02 sensor spots or just the one where the cat would be? Also do you guys have any recommendations for a dp? I really would like to get one that doesn't throw a code after I install it.
you are going to get a cat efficiency codenot ot mention a little over boosting, a un catted down pipe is just a pipe with 2 flanges on it
