One of the requirements from my parents to get a motorcycle was that it had to be loud. Well the stock pipes on my bike are extremely too quiet. I found some Cobra Drag pipes for around $330. I don't have a lot of spare money and that price is close to what I can afford at the moment. I've heard mixed things about drag pipes and straight pipes. What would be the downsides of getting them? Would I have to get the fuel system worked on since it is fuel injected?

Edit: I just realized that it doesn't make sense to buy a quiet bike if loudness is a requirement. The reason I bought the Boulevard is that my father bought the bike and while helping look at bikes for me and my brother he bought himself another one and I bought it for $2000 from him.
