The Exhaust Manifold is vital in GMC Canyon vehicles as it channels hot fumes from the engine to the exhaust system hence regulating efficient engine performance and curtailing toxic gas release. Depending on the type of the engine, the manifold is located in different areas, although its main purpose is to minimize intake reversion, thus restricting the flow of air and contributing to loss of efficiency of the engine. Originate GMC Canyon exhaust manifolds are generally made of cast iron or stainless steel while headers are after market exhaust parts which have higher flow resistance than the traditional exhaust manifolds. These headers enhance the velocity of the gaseous exhausts in the internal combustion engines which in turn enhances efficiency. Over the years, different designs may have been utilized, but the primary function remains consistent: to collect exhaust gases from multiple cylinders and to direct the exhaust gases on through the exhaust while the engine continues to perform at optimal levels and the occupants of the vehicle are safe.
