About this product

GM Genuine Parts Exhaust Muffler Assemblies are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These assemblies have the necessary components to service your vehicle's exhaust muffler. The muffler helps diminish the amount of noise emitted by your vehicle's exhaust system by reflecting the sound waves in such a way that they partially cancel themselves out. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
