Picked up my exhaust pipes from the muffler shop today. I think I made the right choice. Total including the muffler was $153.28. That's front pipe, rear pipe, muffler and a hanger. I installed it all but found that it hangs down too low so I think a little extra bending where it turns under the cab will help it hug closer to the frame.
I'll keep updating as I make progress.
By the way, I have a quick question. Which end of this insert goes towards the manifold?
