G87 Catless Downpipes & Single Midpipe Video
The G87 platform now offers a comprehensive Stainless steel catback exhaust system. As per customer requests, the product utilizes Electronic exhaust valves for a factory-like experience. However, the original G8X valves only partially open, leaving something to be desired. For this reason, we have incorporated a valve controller to provide the option of fully opening your valves.
Drone, anytime the muffler size is reduced from the OEM configuration, the risk of drone increases. This is highly subjective and can vary from user to user. Sound characteristics will also change as muffler size is altered.
