With our cars, its mainly for sound. The stock ecm automatically adjusts to exhaust and intakes which give a barely noticeable gain in HP. If u plan to get a tune from AA or somewhere else then it may give u a slight advantage. e46 cars mainly see exhaust restrictions in the cats which means a full header replacement. Hope this helps...
