Check out the above link if you want to learn more about the exhaust control valve you’re talking about. Everything I've read says the ECV is there so Honda can pass EPA/NTSB standards or what ever regulating authority regulates noise emission standards. You won’t hurt a thing if you remove it properly. Just be sure to leave the servo on the engine which is the part the cables connect back to.
