Bought as a replacement muffler for the 05 Galant LS. The car came with a standard muffler that made a nice low moan. Updated it to aftermarket aloud. For many years tired of how noisy the car drives on the highway. I started the car with this new muffler and couldn't understand for 2 seconds if it turned on or not. This baby is QUIET and makes driving a pleasure. It's also silent on cold starts.
