Does anyone know if the y pipe off a 86 2.9 will fit the exhaust manifolds for a 91 expo 4.0? I can make the rest of it work as long as it'll bolt up to the engine.
 
It should. I was talking to 4.0B2 about two weeks ago asking about his setup and he said he used the 2.9 Y-pipe on his 4.0 swap.
 
Yes, it definitely will. My stock 87 2.9 y-pipe is bolted to my 91 4.0
 
Awesome. Thank You guys.
 
Another confirmed here. My 88 Y-pipe is bolted to my 94 engine...
 
Not that you need me to confirm it but any cologne engine Y-pipe will bolt to any
cologne engine with factory manifolds...

even a 4.0 SOHC Y-pipe bolts onto a 4.0OHV and thus also a 2.9...

I fixed a friends '85 BroncoII with a 2.8 by using a 190 4.0 Y-pipe and
an 89 Ranger (2.9) cat on it...
