Finding one and installing it is easy. If you want to save some money, you could look in the classified sections of car forums like honda-tech.com or craigslist. Install is straight forward. If you have a jack and jack stands, and regular hand tools(ratchet, sockets) and WD40, you can do it in about half an hour. It's just a few bolts that you have to take out. That's why exhausts are considered "bolt-on". Also, if you want loud, get an Apexi N1. I don't condone it, but it's just a suggestion.
