The Chevy guys have had this for decades. My dad had those on our old Chevelle. The only difference they were operated with a cable back then.
I do agree with everyone, unless you go to forced induction(blown or turbo). You are only going to hurt performance with the cut outs. In stock trim you need that back pressure to help with torque.

My cousin has one (the q-tech electric one) on his Firehawk, and he seems to like it. The only problem with the one that you posted is that I've heard that they leak over time, because the little flap inside quits sealing well. I have some with the bolt on plates that you undo by hand, and I havent used them in over a year. I think the car sounds great with my exhaust, and it sounds like an old truck with them open. If you want them though, I'd go for it....just might get old to you after a while though.
