LMAO now we have programmable header corks!!

I don't get how blocking one exhaust tip is going to do much, unless that muffler is divided into two chambers inside, and the side with the valve is a straight pipe? Plus, it looks like it has to be welded in. That will drive away some customers. And they don't even say if it'll add horsepower or not. Anyways, this is kind of a stupid idea.
