Hi I am new to this forum. Any help would be great. I have a 08 impreza wrx hatchback. I want to put in a Nvidia N1 catback exhaust. I am trying to decide between the racing or street version. The online videos don't really help me out too much. Does anyone own one of these in either version? Even any information about which exhaust is "better" would be really helpful. I am also trying to see which one would be louder on the inside of the car. I got mixed reviews about which one is louder.
