So is the E46 M3 rice? There is absolutely no need for a quad setup on that car. There is no need for a dual setup on a 335. There is no need for a quad setup on the e92 M3 or any M5 for that matter. BMW went out of thier way to make them have quad exhausts at the expense of weight and performance. And like I said above Dinan puts fake tips on thier exhausts because they don't want to loose the look.
