Someone please explain this piece of hardware to me. Is it used just to create a dual exhaust set up or what? I know I probably sound like an idiot I am sure their purpose is obvious but I'm kinda in the dark. Enlighten a brutha please.

 

You have one pipe coming out of each side of your engine. These two pipes come down and intersect into one pipe. The rest of your exhaust is just a single exhaust system. Our trucks have a Y-intersection, but many refer to it as a Y-Pipe. One reason is because the intersection can be cut out and replaced by a more efficient Y-Pipe. Another reason is that Y-Pipes are referred to in general for a variety of configurations in many vehicles. Most of the improvements are related to size and flow. If you do a search you will also find pictures.

 

Thanks Max! Which is better though an aftermarket y staying single sll the way or doing a true dual set up?

 

You'll get arguments both ways, but my opinion is a single exhaust on stock to mildly modified F-150s.

 

Thanks Again.

 

Anytime !! Let us know how your upgrade works out.

 

Still a lil' torn between true duals or the y pipe or magnaflow15749. I already have a superchip and airforce one CAI. So this is probably the last expensive performance upgrade I'll do.

 

I've got pics of the factory Y as well as the Magnaflow Y and Flowmaster Y in my gallery.

I recently installed my Spintech exhaust. I checked out the factory y-pipe today before taking it to the dump. I bet the hole for the driverside y is 2 inches or smaller. The x-pipe for the Spintech exhaust is 2.5 inches (minus the thickness of the pipe) all the way through.

I haven't heard the Magnaflow exhaust in person, but the sound clips for any setup probably don't do justice. I was torn between the Magnaflow and the Spintech setups. I loved the Spintech because it exited before the tire and had an X-pipe, but the Magnaflow gave the most HP. Cost eventually came into play, and the Spintech was MUCH cheaper. I wish I would have ordered directly from Spintech, but I absolutely LOVE the way it sounds!

 

You guys are freakin' awesome! Thanks for the pic's and advice.

 

BTW, the jagged hole in the factory Y pipe would only pass a 1/2" drive socket with a(~1 5/8") 1.6" OD. I still have it under my workbench somewhere.

 

Here's another pic just to give you an idea of the general quality of these factory intersections.



And the previous one as well.

 

I thought quality was job one?

 

Mine was the same way. Whoever signed off on that one should be pimp slapped.
