Whether one likes a loud pipe or not is a personal preference. Some like them loud, others do not. I personally like to hear the full sound of the engine, like a deep growl, which means an after-market muffler. This issue has been debated fully on this site, and there is no consensus regarding sound nor a specific after-market muffler. My suggestion is that you do a search of "Battle of the Cans." Then, decide what is best for you.
