I dont know if i have the pics but on a buddies truck we used 2 5 inch stacks welded in a v with a pipe where they met so it smokes even. It didnt look to bad for a quick few hour job

No one makes a kit for putting duals on a 1st gen, I don't know why you would want duals on a inline engine anyway but to each there own. run a single to just before the axle then split.

i've seen a lot of dual stacks on cummins' i'd make a v as soon as possible in the exhaust but this makes it more expensive. you can also do 1 into the bed and split it there but usually it looks bad

I think he is looking for rear exit dual exhaust. Not stacks. At least how I read it.

oh gotcha. well then my question is why? personally i'd just do a passenger side dump in front of the tire. banks might make monster duals i know they do for some. idk about that truck though

---AutoMerged DoublePost---

nevermind i was wrong. banks doesn't and i doubt you'll see anybody that does duals for that truck
