Upgrading your 2007-2011 Mustang GT500 is easy with the help of Stage 3 Motorsports. Your new Shelby GT500 will see huge power gains with a new supercharger pulley, cold air intake, performance tuning, and exhaust modifications.

2007-2011 Mustang GT500 Supercharger Pulleys: Stage 3 Motorsports suggest the steeda or metco 2.6 inch supercharger pulley upgrade. These pulley will take a special tool for removal and installation, we suggest letting a shop do this work.

2007-2011 Mustang GT500 Cold Air Intakes: Adding an intake is easy, the install takes about 1 hour and can be done with common tools. Once you add a cold air intake to your Shelby you will need a performance tune. If you are adding a tune, now if the time to add a smaller supercharger pulley. Adding a cold air intake will also make you exhaust system louder.

2007-2011 Mustang Gt500 Exhaust Upgrades: The stock GT500 exhaust system is far to quiet. We suggest adding at least an axle back exhaust. We see a lot of Shelby GT500 customers really enjoying the sound of the bassani axle back. If you are looking for big power, add a set of GT500 long tube headers and high flow cats.

The Big Picture: If you want big HP numbers from your Shelby GT500 you will need a complete upgrade package. We have a couple pre-packaged kits to help you out. If you are looking for 650+ HP, call us about a GT500 whipple supercharger upgrade.
