It all depends what you are looking for man. Everyones opinion is going to be different. Some like it very loud some do not. Lets start by telling us how much you are trying to spend, if you are trying to go stage 2 with a downpipe or just get a catback, also is your car hatchback or sedan? There are a lot different set-ups that you could go with depending on what you are looking for. Another thing is you can search online all you want for videos but personally and i think everyone on here will agree videos don't do any of the exhausts justice. You are better off trying to find a local subi meet and seeing what other people have to really get a good idea of what they all sound like.
