wrong, if you have a 3 bolt flange then you have a stock flex pipe, the headers and y pipe are a direct swap.
OH i did not know that.. thanks for the info ...

How's it feel to save lots of time & money. The headers will be a direct swap. No flex or other mods needed for the exhaust.
You will only need the fitting for the EGR pipe adaptation - cheap & kinda easy. Of course the MIL eliminators too, but you'll be up & running lots quicker & cheaper.
ENJOY! 
Must be that jumbly-wumbly thing happening again.

yep, 5/8" compression fitting will do the trick.

Ok I guess I understand the whole y-pipe flex pipe deal...
Since I have a early 98 I have the 2 bolt cat.
The W/R y-pipe is shorter then my factory y-pipe. So because of this if I just bought the Trubendz high flow cat testpipe w/3 bolt flange I would have roughly 8" of gap. So to properly correct this I need to get the flex pipe that everyone is talking about.
Is this correct?
Or could I just by the Trubendz cat and be done with it after I build the MIL's and use the 5/8" union fitting?
Or even better could I just buy a 3 bolt flange, weld it to my existing cat and call it good and just use the MIL's and 5/8" union fitting?

Yes, you need a flex pipe.
Just stick with the hi-flow trubendz cat.

Well I'm not quite sure. What's the reason for needing a flex pipe. I just got back under my car to put my new clutch in and I placed the W/R y-pipe in there underneath my existing 2 bolt one and it matched up perfectly. I'm assuming if I buy the new Trubendz cat with the 3 bolt flange it should match up with my existing cat pipe, which would put it right at the W/R y-pipe flange.
So what am I missing here if I need that flex pipe? Will the Trubendz cat be shorter then my existing one? If thats the case wouldn't be easier and cheaper to just weld on a 3 bolt flange to my exisiting cat pipe?(my neighbor is a welder and has a nice setup, plus he owes me a favor.)

Welding a flange right up to the stock cat. Is another solution.
People would rather do all the work themselves. Instead of leaving there exhasut loose. Then driving a leaking car up to the shop to get it welded.
I reject your reality and substitute my own.

the 2 bolt y-pipe allows the engine to move and have it not pull on the exhaust and crack it if it was a solid connection. The 3-bolt cat makes a solid connection so the exhaust needs a way to flex, the "flex" pipe allows the engine to move and not the exhaust like the 2-bolt setup does
so if you have a car with a 2-bolt cat and you want to run the WR y-pipe you need to change your cat to a 3-bolt one and add a flex pipe to make it all work.

So does the trubendz cat allow for the install of the flex-pipe. I guess the real question is, is it shorter then the current 2 bolt cat I have now, so I will have space for a flex pipe to fit in?
Also are there documented cases of peoples ehxaust cracking because of using a three bolt without a flex pipe?
Also I wonder if someone were to use a donut between the two 3 bolt flanges if it would limit the stress on the exhaust. I suppose one would have to use a dremel to allow proper sitting of the donut, but it could be done.

i don't knwo but I would think if you ordered the 3 bolt cat that it would be the correct size to bolt into the stock exhaust, and that would include the flex pipe
