4" exhaust pipe for Banks Turbo

[Clydesdale]

Hi guys,

I have a '93 F350 7.3L with a Banks Turbo and it has the complete Banks 3" exhaust pipe but I want to change the pipe to 4" and then run stacks. I phoned Banks and they don't have any pipes bigger then 3" for my truck so where would I buy a 4" pipe that runs off the Banks Turbo?

Should I just run the stacks off the 3" pipe? I want to change to 4" because I read that the engines get better mileage and it breaths better.

Thanks

Its going to be a custom job. I fabbed up my own exhaust.

If your doing stacks, get a stack kit. That will give you the Y-pipe for the stacks. Drill the hole. No go and purchase some 4" exhaust, that will run between the Y-pipe and the downpipe for the turbo. After that, you will need to buy whatever it takes to make it work.

If you buy all the pieces, I'm sure an exhaust shop could help you.

Thanks for the reply.

I worked at Midas Muffler for 6 years so fabricating it will be a breeze.

One more question about stacks..... when it rains and all that water gets in there, won't that be a problem with the water sitting in the pipe? Will the heat of the exhaust evaporate it eventually?
