If you are ready to stop strangling your powerful engine with a cheap and restrictive OEM exhaust, then you need to install a powerful and reliable Gibson exhaust system. Gibson exhaust systems feature a more side open design than most stock exhausts, which means you will have a significant reduction in back pressure. Back pressure refers to the force it takes for the cylinders to push the exhaust gasses through the exhaust system. Higher back pressures rob power from the engine, so any reduction in back pressure frees up horsepower to drive your wheels. Gibson exhaust systems come in two materials. The aluminum Gibson exhaust system is dipped in an aluminum-silica alloy that creates a rust resistant coating. The stainless steel Gibson exhaust system is corrosion resistant by the nature of the material, and it is constructed out of a high strength, low-carbon steel alloy. All Gibson exhaust systems feature a slip fit design. That means that each component of Gibson exhaust system slides into the next section, ensuring both an excellent fit and a smooth, turbulence free air flow. With a Gibson exhaust system, you can be confident that you are going to get all of the power you need and it will be with you for a long time.
