I won't be able to get the car tuned until the end of the year. Is it safe for me to drive the car with the mods installed or should I re-install some of the OEM parts to be safe? Reading through this forum I've seen mixed responses. Some people say that it should be safe and others say that the A/F ratio could be thrown off really bad. Is it possible that the ART Pipes are reading the A/F mixture incorrectly due to the 02 sensor placement? I'm just trying to be safe and ensure that I don't damage my vehicle. Any help is appreciated!
