I have recently scored an almost free banks turbo for my 1986 6.9 and am looking for a larger exhaust...at least 3". Does anyone know if the exhaust pipe and muffler from a 1994-97 powerstroke has the same bends and length as the stock 2 1/2" pipe. I could do some minor modifications if necessary. The junk yard up the road says they have one, but I don't want to pull it without a fair idea it will fit.

I reckon it would be the same assuming that the truck is configured the same as yours.

 

Yes , the later model OBS exhaust will work on the older model. I have a 88' F350 and I installed a 3in down pipe with a 4in exhaust. With the 3in down pipe, you will have to rework the fire wall where it passes some.

 

you will have to cut or bend back the body seam on the firewall for it to clear and maybe use a little persuasion tactics with a hammer on the firewall
