thats exactly what i did, i have a true dual 40 series exactly as you want, whats your email? i can try to dig up some pix of the fab work, or just take some tomorrow in the sunlight, but it wasnt hard, they exit right b4 the passenger rear door, fun project. they hang a lil low, but my new body lift that i am waiting to install will eat that away, the h pipe is on just as the two pipes turn to go towards the back of the truck, then the mufflers pretty much straight to the h pipe. i get lots of compliments and turn alot of heads, plus i can hear the wifey come home from about a block away, and thats tight... anyways i will get you some pix, any questions just let me know,
Chris
