The Y-pipe does fit, I know it is amazing. Considering the fact that I had problems too. At first I thought the flex pipe flange was warped (becasue it would not seal and it sounded like i had no exhaust) so i got a hold of Nick and he sent me another, well it was doing the same thing it turned out the be that I had the wrong size gasket, I then got one from autozone and viola it was sealed and I had some trouble with the 02 sensor holes but i end up going back to the original Y-pipe that he had sent me and it works perfectally with the new gasket.

Well fear not duratec owners me a nick are working on a revised y-pipe. I am sending him my stock y-pipe so that he will have it to take meausurements. Hopefully it will work out and we wont have so much difference between pipes built of the same jig.

or you could just buy the y pipe from ford, cause my Duratec engine come with a y pipe from the factory and I got dual exhaust...
The duratec performance y-pipe has bigger pipes and no cats. And it's probably a lot cheaper than anything you'll get from Ford.

I was quoted 1000 dollars from ford and that was a discount through my school.

The duratec performance y-pipe is 300 dollars

When mine didn't fit, just one or two things were wrong. Just barely, but it was still enough for it to not fit properly. Things could have moved slightly during the final process of making each indiviual one. Which is what probably happened with mine

i have one that seems to fit perfectly but the other one they sent barley fit.

O2 sensors were hard to get in, bank2 sensor2 was at such an angle that if i did not tape the wires down that they would have hit bank 1's pipe.

Face it guys we have to work this out with them. There are no other places making a high flow y-pipe so we are at a loss if we don't try.

DP is not Borla and they don't have one of these cars sitting around or the extra money to buy one. there is only one guy down in so cal willing to test fit there stuff and he can't be without his car for very long.

Nikolas is a good guy and is trying as hard as he can to get these projects done. I talk with him every couple of weeks.

. One of the O2 sensors was in the wrong place. Just by a half inch. Where it was, the senors was hitting the tranny and that's no good. And you can clearly see where it bolts up to the flex pipe, it off by 2-3 inches. Even though the flex pipe would bend to fit, it's not a correct fit. So no good. Broke 2 O2 senors in the process. I'm very lucky there were a couple y-pipes lying around with senors in'm.[/b]
Dman was the O2sensor off like how i described?

ON the flex pipe flange how was that off 2-3 inches mine bolted right up no bending necessary and the second one bolted up fine?
could you draw a picture or something along that line?

i do have to agree the the o2s sensor holes were a bit tight at least both upstreams were.

Not to change the subject about the fit of the Y-Pipe, but has anyone who has installed one noticed a performance difference? Or, has the fit been so bad that you just had to remove it and never had a chance to drive the car to test out the performance gain? I think the Duratec Performance site was claiming 15 hp increase at the wheels, which would be a huge improvement for just a y-pipe, IMO.

I know Damon (Duratecchie) has a pic of the pipe installed, minus the O2 sensors beening in. With this pic you can clearly see the connection for the felx pipe and the 3" flange is off by a couple of inches. The pic is in the old forums, but I SUCK at the computer, so someone maybe Damon could put up another pic of what I described??

I can't exactly draw a pic of the O2 sensors that were in the wrong place, but maybe this desciption will help. By looking at the pic of the catless y-pipe, on the longer pipe, the O2 sensor that is after where the cat is supposed to be, the 90 degree bend for the smaller pipe is too close to fit the sensor in. The 90 degree bend on the pipe had to be dented a little so the sensor would screw in and not hit the bend on the other pipe.

well somehow we are going to have to find that pic because for some reason i can't see it on the old forum. But the picture supplied by Damon in this post the flange looks exactly like mine on the y-pipe and it fits perfectly not off one bit. I would almost bet that the flange on the 98/99 is straight where as the 96/97's are cocked the one way.

ON y-pipe number 2 the O2 sensor was almost not able to fit and it is the same one as D Man described

but the one currently on my car fits perfectly in every which way

I do notice a difference in power all through the power band but my car is a terrible test car first because I am still waiting for diablo to make me a new program for my chip and it just is not going to happen, and two my car just does not ever act positivley to any mods at least not like Venom's 99.

Am I right in assuming that D Man also purchased the DP high flow y-pipe along with damon and me.

I guess I have the only successful install and only 4 pipes were made and I ended up with two of them.

I installed the thing the day after I got it and did it on the grass and leaves in my backyard with the car on ramps and that was not easy ecspecially since I am not small in the chest and the pipe had to come out with me it is a not to easy to remove that thing without a lift and an impact gun.

Might just be more trouble than it is worth at the moment but give Nik sometime and we will try to make a perfect one. I would alomost say that it was the welders fault because he made 2 right and 3 wrong that is if you count the proto-type.

I went and checked the old forums and the pics are missing. It was in the old forums, North East chapter, 11/22 meet, but all the pics are missing.

I think it was off because, maybe a bend further up the pipe was off by a little and that mulitplied by the time it got to the end, just a guess.

I have been trying to call Nick but get his machine, he caslled me once and got my machine( went to the movies and saw the Return of the King). So hopefully I could send it back and get some sort of store credit or something.

Nik is sometimes hard to get a hold of but you just gotta keep trying.

The Line that you call him on is also the line he uses for the internet.

he has actually had some problems with stuff on his own vehicles from the same welder maybe it is time to find a welder (type Person).

If he can get a everything lined out he might be able to give you a revised one when it is done atleast he did say that he would exchange with me so I am more than sure that he would do the same for the both of you.

  Yeah, but that's why they call it a flex pipe [/b]
Not quite.

It is not supposed bend to fit.

it is there to allow flex in the exhaust when the motor twists.

I blame myself for some of the mishap. As you know I was the donor for the first y-pipe and I did the first prototype. there was some modifications that were needed after the first one was made, but unfortunatly I became busy and I didn't have the time to drop my y-pipe again and try to fit again. I know nick was under pressure to get these things out so my bad
. After hearing that some of the people were having problems with the fitings I am hoping we can get this resolved by getting a better fitting and hopefully some highflow cats too.
here are some pics when I put the first prototype on.
