    Improve Horsepower And Torque. The Kooks Long Tube Header and Off-road Shorty X-pipe combo kit for the automatic 2005 to 2010 GT Mustangs will balance out the exhaust pressure to increase flow over the restrictive factory exhaust system resulting in more horsepower, torque, and better throttle response.
