up pipe gasket question
Now that I have my up pipes and babys butt off the truck can someone please explain how this stupid design doesn't leak from new...
You mean to tell me that the only thing that keeps these pipes from leaking is how snug the gasket fits to the pipe? And this joint has to give a little for expansion?
For a second I thought about using a little exhaust paste, but if the pipe has to move then that would be a waste of time correct?
Who ever thought of this design should be shot at sunrise....possibly by the guy who thought up the bellow idea.
No, I'm not buying $800 bellowed pipes, or a $2500 late turbo conversion. I'll make this work with a little advise from yall.
So the trick is to expand the pipe big enough to snug the gasket, but still slip in the babys butt (get your mind out of the gutter)

Hook it, I'll pull it.

Frank, the problem with the stock up-pipes is they tend to bend the pipe where the gasket fits on it. If you look at your pipe where the gasket sets, you will see how the pipe is bent in to the shape of the gasket. That is what causes the new gaskets to leak again.
Well, thats how mine looked when I put my bellows on.

Frank just expand the pipe so the gasket is tight to pipe. Don't worry about movement from heat, it will happen at such a small amount it shouldn't loosen up for at least 50k-100k as long as you get gasket tight to pipe.
So what do the end of your pipes look like ? If they are bad it is a very good chance it will leak sooner than later.

Rick, Ed my pipes aren't creased or bent in any way. There are straight and smooth, but you can definetly tell there has been some movement or slip-age between the pipe and gasket.
I'll make sure they fit nice and snug around the new gaskets
Thanks you for the clarity.
I still think it's a stupid design...just sayin.

I had my H2e turbo installed by WOP in 2007. They used exhaust paste on the donuts. No leaks! May be cheap insurance?

It is a stupid, unthought out idea but it is the "old school thinking" But what makes me even more MAD 
is the fact that they bend over the poor guy with a E99 to replace with stock or IH pipes.
So far the bellow are hopefully helping but time will tell. And if mine start to leak I am actually thinking of going back to stock donut gaskets and expand the pipe even tighter. I wasn't overly impressed with the FelPro gaskets but many here on FTE have said good things so I am giving them a go.
Now I am sure it can't hurt using exhaust paste and I am sure WOP knows more about leakie donut gaskets than I. But do remember what the donut gaskets looked like?? Where they blue like a FelPro or where they silver like stock donut gaskets?? I ask because I wonder if the exhaust paste works better with stock gasket material. Because I think that is kinda what the blue stuff in the FelPro acts like?? I am guessing I don't have a clue. But bringing up exhaust paste really has me wondering the merits of using it depending on the gasket material itself.

My pipes weren't bent or deformed either. They were smooth and black (from the soot). I simply cleaned the pipes with a Scotchbrite pad by scrubbing AROUND the pipe....not lengthwise. I had originally purchased the Felpro gaskets since they are less expensive but they were too thick. The OEM Ford gaskets are the correct profile to fit completely inside the compression flange and the housing. In doing so, the gasket gets 'crushed' so it seals tightly around the straight pipe.
Not sure how long it will last since it hasn't been that long since I changed them out. Maybe 20k miles....
No leaks yet...Here are some photos.

Greg, I have the Felpro's and after comparing them to the originals I don't see the benefit to a thicker gasket either
The I.D. makes all the difference weather these pipes will leak or not, and the Felpro's have the same I.D. as the originals.
Maybe I'm over thinking this I'll just put it all together and see what happens.
My turbo rebuild kit comes in tomorrow, so I'll prob have a few more questions about that...

Thanks for those photos, Greg. That is exactly the info I was looking for...
The new ones look thicker. Is that because the old one is crushed, or did Ford change the specifications on it?

I'm not even sure what the stockers cost off hand.

The spec is the same, it's just that the new gasket gets crushed by the flange when it mates up to the collector. If I was to pull out the new one then it would be about as thin as the original piece. It has 'scrim' (a weave like material) inside the gasket media that allows it to crush but not crumble.

That is the painful part. My dealer bent me over the counter and didn't even bother to lube me up. I think those gaskets were $18.....each. 
Clay can probably get a much better deal.....or maybe Tousley Ford.
