exhaust cutouts, worth it?

I have electric exhaust cutouts on my Demon and I love them. It's not for any HP gain it's the pure fun of opening them up any time you want to and look at peoples expressions. One of my favorite times to open them is when I'm beside some punk playing their dumb *** music way to loud I open them and give them the finger.
They are one of the best things on the Demon to enjoy anytime I want
