Completed today, I'm very happy with what has been achieved.
The huge concern in winters was warming up the truck while packing the trunk with the tailgate open. All the fumes went into the cabin where kids were already, which is not ok obviously.
parts used:
amazon:
* elbow 45 3": Dynomax 42760 Aluminized Elbow
* pipe tip: Dynomax 36474 Stainless Steel Tip
canadian tire:
* two standard U clamps 3"
* universal hanger, actually half of it, bent to the place, I used the lower hole with the speedclip left from the original hanger.
the longest and hardest part of the task was to take the resonator out. 6 year old exhaust was baked in rust and the clamp bolt rounded up in no time. Angle grinder solved the clamp bold, pry bar helped to rotate the resonator back and forth and eventually it dropped.
No more poisoning kids while loading groceries or sleds! Highly recommend, total was under $150 CAD
