The way my exhaust it set up now is a 3 inch pipe from the y straight to a single stack. I was thinking about doing a true dual system. I want to remove the factory y pipe and run individual pipes from the manifolds and turn em up in to there own stack in the bed. I plan to turbo the truck eventually so I kno I can't have that set up but for now I want to do it jus to see how it will sound/ perform and jus to say I did it. Tell me what yall think. I'm thinkin ill need to use 2.5 inch pipe to creat the back preaseure

 

thats the same plans i wanna do

 

I wanted to do the same thing. I never really looked to see what it would take to do, but since I take my truck out in the hills and play, I didn't want to run the pipe under the frame rail. I thought about cutting out a hole, welding in a piece of pipe, then putting flex pipe on both sides, then running the pipe to the bed outside the frame rail and up.

Like I said, I never really checked into doing it that way but its an idea.

 

You could do something like this...its 4" pipe but you could run it down the frame rails. I have move mine inboard back under to stock placement now but you get the idea. And yeah flex pipe makes life a lot easier.

sounds good man, post pics and let us know what you think if you do do it!!!

 

pretty sure you dont need that kind of back pressure and besides those factory exhaust manifolds have plenty

 

these trucks need about as much back pressure as a 50 gallon drum provides. In other words...ZERO needed.
