The Gibson Dual‑Extreme cat‑back exhaust for 2008–2009 Chevrolet Silverado 1500 LS 4.8L offers an aggressive angled exit and a bold street tone. Dyno‑tested to produce average gains of 15–20 horsepower, it pairs a Superflow muffler with polished stainless tips for a mean sound. The bolt‑on system installs with factory‑style hangers, uses mandrel‑bent stainless tubing to limit drone and is backed by a Lifetime Limited Warranty.
