Ive got a 94 f250 turbo diesel. Not a powerstroke. I've been looking to get a new exhaust system. I've got a straight pipe now but it's the stock piping. I'm wanting to go 4 inch or bigger. Would a powerstroke pipe work?

 

Get the correct down pipe from Banks and the rest of what ever exhaust sytem you want to use will work

 

If you have the factory ford turbo setup, it's basically an ATS system. The only real difference is ford put a stupid smaller crushed downpipe on their version. You should still be able to get the 3" downpipe conversion piece from ATS. The 3" pipe takes some massaging of the firewall to fit, but once you get it down far enough you can step up to a 4" pipe under the rest of the truck.
