I spent the better part of saturday putting on a 4" turbo back stainless exhaust on my Diesel F-350 dually,it sits high enough off the ground that you can do it without much problem,the hard part was getting the old down pipe out of the engine compartment,I had to cut it with a sawzall into three parts.There was a firewall seam that had to be bent down to make room for the 4" down pipe so I took a scissor jack and air hammer and made short work of that,overall it did increase HP and sounds awesome,these Diesels are so easy to make HP with.

 

good project. my neighbor stuck his pipe out the back of his cab, and boy was it noisy. I could hear him almost a mile away. very crisp sound.

 

It sure makes the Turbo whistle louder.

 

nice work bro how much is the stainless exhaust?
