Alright, this might have been talked about before but just bear with me. When an off road h pipe is installed with no cats and a cat back exhaust system, whould it smoke any? Just wondering because there is a car with this set up and the guy said that it is supposed to do that and I am not sure considering I have never had this set up. Just let me know what you guys think!! also it doesnt smoke all the time just when you get on it.
