Yes a cutout will be loud, but the benefit is being able to close it when you factory sound. As far as performance it will be like running open headers so there is a gain there especially when it comes to a LS based engine. You are only talking about maybe spending 50ish dollars with install. So it's not like you are losing a whole lot if you decide you don't like it.
