The perfect premium solution for styling out the rear profile and amplifying the sound signature of your G8X without replacing the entire middle pipe layout. The IRL Valved Axleback bolts up perfectly to the factory midsection and interfaces seamlessly with the stock electronic valve actuators. Open them up for an immediate, throaty growl that lets the S58 engine breathe, or shut them down to maintain total factory comfort. Completed with massive high-finish quad exhaust tips that fill out the factory rear diffuser perfectly.
