They sound badass, look great and I believe they're even the best value for the money (they come with silencers already in, plus an extra means to silence, and a decat pipe). Only problem is the installation, I had a hell of a time aligning them and had to grind down a bracket to make it fit right. If you're going to have them professionally installed, this isn't a factor, but it helps to know your stuff if you're going to do it yourself.
