Honestly, you can do that, but there are much cheaper ways of making a better flowing intake. I took the air inlet restrictor off my stock airbox and then installed a K&N filter in it. Then I took the air silencer out and cut the guts out of it. It basically makes it a high-flow intake as there are no restrictions in it anymore. I did notice a gain in power and throttle response, especially when the engine was under load.
