Engineered to enhance the natural character of the 6.2L V8, the Walkinshaw Performance Cat Back Exhaust transforms the sound and presence of the GMC Yukon Denali. Constructed from high quality 409 stainless steel, the single 3” into twin 2½” configuration is designed to optimise exhaust flow and deliver a deep, controlled V8 note under acceleration—while maintaining quiet, refined in cabin comfort during cruising.

Carefully tuned for low noise, vibration, and harshness (NVH), the system ensures long distance comfort and everyday usability are preserved, making it ideally suited to both urban driving and extended touring. Finished with quad shadow chrome tips, the system adds a subtle yet purposeful visual statement that complements the Yukon Denali’s premium styling.
