Originally introduced in 1987 as a special trim of the GMC CK pickup series, the GMC Sierra became a distinct model in 1998, deeply influencing the development of the pickup truck market at the beginning of the new millennium. The Sierra started its career as a solidly built and reliable worker, having turned in a few years into a sophisticated and fully equipped vehicle, suitable for different purposes: good combination of towing capacity, power and comfort has made the Sierra a versatile truck, apt for work, family, or recreational uses. The current generation of the GMC Sierra premiered in 2014, being a superb muscular truck with a massive road presence. Offered in several cab/bed configurations and available with different strong engines, the GMC Sierra is a proven leader in its market segment.
Once combustion has taken place, the exhaust manifold enters the scene, collecting the exhaust gases and conveying them to the exhaust system, where they are disposed of. A good shape of the exhaust manifold is therefore vital for the proper function of both the engine and the exhaust system. At our online shop, we offer a very good choice of GMC Sierra exhaust manifolds and related components, flanges, gaskets and hardware. Also we provide qualified and trustworthy customer service, available for questions and further info at the online Help Center.
