Outstanding service, fits like a glove, I should have stepped it up for a more richer sound, but I was being cheap! Sounds quite but that is what I requested!

Great sounding muffler, nice deep tone, just make sure you have a tail pipe that leads past the rear axle. I had mine dumping out right under the passenger seat. Shook the damn jeep and you couldn't hear anything. Added the tail pipe, great sound now.

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.
