An aftermarket muffler for the RSX refers to a replacement exhaust component designed to enhance the performance, sound, and aesthetic appeal of the Acura RSX vehicle beyond the factory-installed muffler. Aftermarket mufflers are typically made from higher-quality materials and are engineered to improve exhaust flow, which can lead to better engine performance.
