When looking at performance cars and custom cars, you often see exhaust headers, also known as exhaust gaskets, replacing cast iron manifolds. Exhaust headers are known to improve performance by flowing more efficiently and increasing the potential for torque and horsepower. Exhaust headers also produce more heat than cast iron manifolds, and this extra heat is not good for either performance or nearby components in GMC, C25s. To compensate for this, exhaust gaskets can be wrapped in header tape or be ceramic coated. Headers frequently need to be replaced, and if the headers in your GMC, C25 are not performing correctly, our website has the replacement parts to bring them back up to speed.
