exhaust
wats up guys i have a couple questions about changing my exhaust out. first let me say that my exhaust is starting to rust through and needs to be changed. i would like to know what would be better dual 3" pipes or a single 4" pipe with the y pipe redone. also what is the differance between aluminized and stainless steel exhaust pipe.

The difference in the stainless and aluminum pipe is a lot of dollars.
Yes the stainless will last longer, looks shiny longer and all that, but you can replace several aluminumized exhaust systems for the price difference.
I would go with a single pipe, either 3 or 4 inch. The front fuel tank makes running true duals a little hard to do.

Ok, I found out that the Banks turbo I have might not work out (something wrong with the turbo internally). I am thinking about possibly getting those diesel headers that were posted up on another thread and run 3" true duels up to 3-4" stacks in the bed. Would this work? I have a 1991 F250 7.3 w/ 2wd.

Something to consider about pipes.
Adding the radius of a pipe to the diameter in round numbers doubles the area of the pipe.
So if you had a 2 inch pipe, the radius is 1 inch.
So two plus one equals three, a three inch pipe has about twice as much area as a two inch pipe.
Since the area is double, either you can flow twice as much volume at the same pressure or you can flow the same volume at 1/2 the pressure.
A single 4.5 inch pipe has the same area as two 3 inch pipes.
