the daytona has 5 extra hp from a factory installed "high flow exhaust"...or so says the brochures...

i think that alot of people jump on things that tack on 5-8hp here and there because they dont require any real permanent modifications or mechanical knowledge. things like a catback system, CAI, etc....people can find a friend who owns a few tools (if they dont) and it makes the car sound faster, and to that person, it feels a little faster.
