i have looked into this myself because i would love to do it but dual exhaust on the 4.2 is really tricky. the space between the rear axle and the gas tank is really slim and you need clearence on each side for heat. the reason the ss has the ability to do the dual exhaust is because the gas tank was shifted a few inches forard. this has been my research but if you find anything new that would make it possible PLEASE let me know i dream about dual exhaust
