Introducing the IRL Stainless Steel Catback Exhaust System for the G8X platform, developed to deliver improved performance, weight reduction, and a more aggressive exhaust note while maintaining daily drivability.

This system features integrated electronic exhaust valves that are capable of fully opening, unlike the factory G8X valves which do not achieve 100 percent open position. For added control, a valve controller is included, allowing you to open the valves completely on demand for maximum sound and flow.

Constructed from high quality stainless steel, the system is approximately 24 pounds lighter than the OEM exhaust. The fully clamp on design requires no welding and is 100 percent reversible, allowing you to return the vehicle to stock at any time. An extended exhaust brace is included to provide additional clearance.

Please note that reducing muffler size compared to the OEM configuration can increase the likelihood of drone. Drone levels and overall sound characteristics are subjective and may vary depending on vehicle setup and driver preference.
