What in the hell the point of a Cut-Out, and what are the gains/losses If any?

Thanks! Sorry for the ignorant question in advance!

Doesn't matter how big they make the fonts on the Stickys, people aren't going to read them these days.

The cutouts allow you to bypass your mufflers by opening a hole in the exhaust upstream. They will give you a couple horses and allow you to make your car obnoxiously loud at the push of a button.

It's not realy THAT loud with stock manifolds though. Also did anyone notice a decrease in mpg? It seems like i've had worse gas mileage since getting it installed but i havnt verified it yet. Would a bad weld job make your mpg decrease?
