This package will make more power then the Racer package. The Racer package does not include an uppipe,or header, which are huge power gainer/turbo spool items. It really is a matter of opinion. You will make raw power from uppipe/header/turboback.. where as IC hoses/STi scoop are nice, but won't really give you power.
