Where can i find a decent Y pipe for a 92 F250 with a 351? Want to keep a single exhaust but the cat is ready to go.

 

What are you trying to do? Are the pipes from the manifolds to the cat bad? If they are then a shop can make you another one. My son's 96 had a horrible hack job done by the previous owner and this is what we did. You can leave out the cat. Flowmaster makes a great Y pipe if you want to fab up something with that. http://www.summitracing.com/parts/FLO-Y214300/ Walker makes a replacement OEM pipe: Walker Exhaust 40585 - Walker Direct Fit H-Pipes - Overview - SummitRacing.com

 

I'm basically wanting to remove the cat but maintain my single exhaust. So I need a Y to transistion the duals comming into the cat junction to the single out of the cat.

 

You're going to have to make it. Either use the Flowmaster Y or cut the cat right after the flange and go from there.
