Product Description

The Gibson 616518B Black Elite is a single-side cat-back exhaust built for the 2020-2026 Silverado and Sierra 2500HD/3500HD with the 6.6L gas V8. Mandrel-bent stainless tubing and a baffled Superflow muffler are engineered to reduce backpressure and add low-end torque and horsepower without excessive cabin drone.

The Black Elite Series tip carries Gibson's exclusive black finish process on T-304 stainless steel for a stealthier look than the standard polished line, while still delivering the same dyno-proven power gains. It's a straightforward bolt-on install with all factory hangers and clamps included, backed by a lifetime limited warranty.
