Hey guys I am looking to buy a downpipe but i cant decide whether to go with catted or catless. I am thinking i am going catless but can anyone give me details about the ERZ. Would it be better to get the ERZ or an Invidia or maybe something else. Also it would be helpful if someone could give me a link of a wrx with a stock exhaust and a catless dp because I want to hear how it sounds before I decide what to buy. All of the videos I have seen someone has an exhaust too, I just want to hear the difference with just the dp.
