Cherry Bomb Extreme 7480 drove my 2012 jku Sport Limited (3.6). For those of you considering this option, do it! Smooth, deep, creaky or rather reserved. Your right foot/thin pedal controls the intensity of the sound - fuel consumption is reduced because I'm addicted to the sweet sounds of Cherry Bomb! No buzz, just guttural sweetness! I do a lot of off-road driving, this muffler lifts up and doesn't get in the way, but its length is just right for venting the exhaust out the back of the jeepโฆ
