I was under my dad's truck looking at the y-pipe, so I decided to snap a few pics for those who are unfamiliar with its design. I have to say it really is bad, and confusing why Ford did it.

I noticed that the pipes from the stock manifolds are equal length, so I'd imagine this is important to maintain when changing the stock y-pipe, because I know from other cars that equal length primaries to the Y affect the sound of the engine quite a bit (unequal = crappy sound). Any recommendations on fixing this? I've looked at some pics, but I didn't know if there were different ways people have changed it.

Jeez, i thought my 2000 y-pipe sucked, that one has to suck even more.

 

Nick, could you email me and tell me how you put pic's in your thread? I've been trying and unsuccessfull.

He just posted URLs though.

I changed the URL of his truck to an embedded image using the [ img ] URL of truck [ /img ] method.

Understand?

 

Yeah, I just loaded my pics onto the free www.lightbox7.com website and, altho it shrinks them down a bit, it is free.

The y-pipe is horrible, I can't believe they purposely pinch it down to 2" or less for no reason, and the 90 degree angle they join at! Duh Ford!

There was a reason.

"Flutter" plagued early V10s.

Ford's response (although stupid in design) worked to virtually eliminate it from later models. The necked down area increases the velocity of the exhaust gas from the right back to prevent the collision of the exhaust pulses at the Y and the noise (flutter) they created.

 

Ah, ok. I know what you mean, my dad's previous truck did have the flutter sound quite a bit. However, I would rather have the flutter and more power than I would have it quiet and no power.

Even after i got rid of the y pipe i had exhaust flutter, did not leave till i installed the headers.Ford could have done something different.I remember when my truck was new, i looked under my truck and saw that y-pipe and i said to myself "THAT WONT BE THERE LONG!"
