Guys heres the deal. I have been working with a local speed shop called Speed Addiction located in PA to make a custom y-pipe. Today they looked under the car to get a basic idea of what it entails. Tomorrow I drop the car off so the stock y-pipe can be removed and a new one can be made. He said as long as there are no unexpected issues it should be no problem.

The pipe will be bolt on, made out of 2.5 inch stainless steel, there will be no precats and it will include a flex section. If there are any O2 sensors on the stock pipe he will be able to mount them on the new one.

If all goes well he said he will be able to produce these in numbers for us. Price cannot be determined until after tomorrow when the first one is done.

I know how most of you guys are and will want to see dyno's, my problem is I don'd have access to a dyno. If the pipe works someone may need to be a test dummy for it.

I do not have any extensive experience with this kind of stuff so if anyone has any suggestions for me tomorrow please let me know.

 

I would suggest to use different flex section than the traditional mesh wire kind...and locate the flex close to the cat for easier visual inspection of the flex if something's not right

stillen's new pipe has a new design, they move the flex to the middle and it is hard to check constriction now. The new pipe still have fitting issue, I have to bent the holder a bit from the hanger near the cat or otherwise, it will make funny noise when I brake.

 

The guy mentioned that perhaps he could try and make the pipe without the mesh in it. I am not an expert on this but would that be ok, I imagine that there may be fitment issues without a flex section

 

Make sure the collector is not crushed. Or at least not much. If both sides are 2" tubing without being crushed at the collector it should meet the flow requirements of a n/a 3.5 stock heads/cam engine. All cuts should be deburred and all weld slag/build up in the flow passage should be ground away.

Get some good pics and post them for us!

 

Just a heads up.. If you remove the front precat you have to relocate 2 o2 sensors to behind your main cat. And aslo good luck getting the pre-cats off, mine where absolutly impossible to remove, I ended up just taking the whole manifold and precat off in one piece.

 

I was under the impression the precats were on the y-pipe. If they are not then they will not be removed. Are there any O2 sensors on the y-pipe itself that will have to be relocated.

 

If the pre-cats stay on then your o2 sensors will be all set. So the Y-pipe your talking about will be like WSP's.. Not a real Y-pipe but it still seems to offer good gians still.

 

Emax95 check your PM

 

There is one 02 sensor in the Y pipe of a 2K2. You can see the coupling in this pic of my Y pipe. http://www.mustangmods.com/publish/8850//WarpSpeedY.JPG

The precats have one 02 sensor each.

 

Thanks for the info, is that pipe 2 or 2.5 inches wide?

 

The two WarpSpeed pipes connecting the precats are 2". Down stream of the collector and the B pipe are 2 1/2".

 

No need for a dyno man. Y-pipes are proven to have gains, and unless your shop is making absolute crap, there's no reason to believe that they won't provide gains like the other y-pipes. After all, it's not so much the construction that gives gain, it's the lack of pre-cats.

 

The flex section is, well, so it can flex. There's a lot of vibration going through that pipe, it will make a racket and even break without the flex.

I am bringing the car in tomorrow instead of today. After speaking with him again I dont think he will be removing the precats so this pipe will be similar to the warpspeed-pipe.
