I'm assuming you got a 'Cat-Back' system that starts behind your catalytic converter and goes all the way back.You will notice a bit more upper RPM power with just that. The header will open it up even more, but there is no need for the header if you plan on going turbo later on. Or, if you really want to get a header, buy a used one in the classifieds or wherever you can find one.
