Due to popular demand our ZR2 exhaust is on back order.  Approximately 4 weeks at present.

Upgrade your ZR2 Silverado with the KM Exhaust System—a precision-engineered, Australian-made exhaust upgrade that replaces the factory mid-section with a high-performance alternative, while fully retaining the factory electronic valve control via your dashboard.

Crafted from premium 409 stainless steel, this system offers superior resistance to rust and fatigue, making it ideal for harsh Australian conditions. Whether you’re towing, cruising, or chasing that louder V8 note, this system delivers a “loud and louder” experience—all while maintaining OEM functionality.

When the valve is closed, the KM Exhaust functions as an anti-drone J-pipe, providing a comfortable ride during everyday driving. Open the valve, and you’re rewarded with a throaty, powerful exhaust tone.

Installation is very simple thanks to the cut-and-clamp design—no welding required. A full step-by-step installation guide is available via our Youtube Channel. (You can find the video here)
