Tell them you are boosting them right now. And to give you the cheaper price.

The sound in that video is pretty mean. I have to say that I as a rule do not like the exhaust options for the JK. Each really is not an improvement over stock.

If you get one, give us an opinion about 6 months after install. Everyone loves whatever they are putting on that day. Live with it for a while, and then decide if you love it. And do not throw out your stock exhaust. You may be sorry later.
