The sound is deep and throaty. I gained about 2 mpg with a catback exhaust replacement. Maybe not the best value for the money, but the quality is worth it.

The 12579 is a large case single inlet, single outlet muffler. Internally the exhaust is split running the length of the case rejoining before exiting. The muffler has a nice quiet rumble at idle with no drone at speed. It has a nice performance sound when the throttle blades are opened wide. Install consists of headers, 2 1/4" to 3" Y-pipe, 3" through remainder.
