This diffuser is designed to give a crisp carbon fiber accent to all 2005-2013 Corvette C6 models. The diffuser is designed to replace the factory diffuser on the Corvette C6, and it fits seamlessly with the vehicle's body lines. Reusing the factory reverse light housings, you do not lose any functionality or performance with this upgrade - all pro's with no con's! With mounting holes pre-drilled, install couldn't be easier!
