Exclamation Stock manifold to headers 1994 F250 351w

Hey everybody. I'm looking at buying a 1994 F250 reg cab LB with the orginal 351w and a 5 spd manual tranny. The stock exhaust manifolds were leaking says the guy, so he replaced them with headers last month. The headers are in good shape, but I have a question. The guy who's selling it didn't reconnect the exhaust. I can see the headers, then I lose sight of them behind the suspension. Then behind the front wheels there sticks two pieces of 3 or 3 1/2 inch flexi-pipe (one on each side) running down towards the exhaust pipes. The exhaust is two pipes, 3 inch i think, side by side. He says that I would have to cut the exhaust about 3 inches shorter, and connect the flex-pipe, and put some clamps on it. Whats the verdict, crap or truth?

They look like shorty headers. They will bolt up to thee stock y-pipe. Unless he did away w the y-pipe

Why would it have a Y pipe? It runs two pipes from the headers back to the cat and muffler...? Heres a diagram I tried to draw, see if it helps.... Thanks

Because that is the whole point of running shorty headers, to keep the y-pipe. If you didnt want to keep the y-pipe and run true duals then long tube headers would be the headers of choice


But hey, you looked at the truck. If you cant figure it out by looking at it then there is no way in hell you can explain it to us to help you out

Sorry man. I didn't mean to sound like, condescending or something. I just don't understand. Where would the y pipe be? Y pipes are two into one, right? Or am I totally off base? I have no clue. Is it up closer to the headers than where I am looking?

Yes. the y-pipe comes off the manifolds(or shorty headers) and into one pipe, then the cat, then the muffler then the pipe continues out the back of the truck.

How old are you?

I am 16, looking at buying my first truck for plowing. My only auto work experience is from working on my 02 Saab 9-5, and even then, all i've worked on is the cooling system.

As for the y pipe, are you saying it goes, from fron to back,

engine, headers, y pipe, single exhaust pipe, cat, muffler, tail pipe?

what happens if there are two exhaust pipes?

Sounds like the truck is missing the Y pipe, you could fabricate one but Bassani makes one with and without a cat depending upon your needs, a few guys here have installed and like them.
