The Muffler is an extremely important part of this car and has a fame of being easy to rely on among other Equinox models. Intended to adequately direct the toxic fumes far from the vista of the occupants, the Muffler reduces the noise of the engine by deploying specific passages and chambers to 'extinguishing' sound waves. Not only does it serve this important aspect to improve the driving experience but also serves as one of the most vital safety/comfort features in a car. Categorized into direct fit and universal, the Muffler is made of long-lasting materials such as stainless steel and aluminized steel. The direct fit option is designed to ensure a perfect fit and installation will not be a problem while on the other side the original sound quality is retained, many Equinox owners prefer this option. Also, some models may have extra resonators for still better noise reduction, especially in those vehicles classified as luxury. Muffler is thus particularly unique when marketed in the auto market since it helps in improving on the efficiency of vehicles that use it while at the same time ensuring that the interior is less noisy. Because of the three generations of the Chevrolet Equinox, the Muffler matching different generations has changed with the engines, transmission systems, and become a reliable vehicle for drivers. In conclusion, the Muffler reflects quality, performance as well as safety of car's brand, which are among the aspects that make Chevrolet Equinox enjoyable to own.
