Ok we discussed it w/ Lupe offline, and I think came to an agreement about the issue. There is no disagreement on the issue, and I ask everyone else to please let it rest.
But since this thread does not die, let me give a straight answer to whatever good there is in the question.
Since we do not know sh!t about what happened to the horsepower of psychojetpilot let's practice what we preach and do a little search. Lo and behold,
here's an interesting thread.
So we now know that the car in question is Duratec, that it has an ATX, and that it was somehow possible to blow a flexpipe.
Well, three issues come to mind:
1. The main cat is plugged to the point that it's possible to blow up a flex pipe (I can't see how it can be, but hey), and it affects the power in the way as posted.
2. The motor mount(s) are broken, and it was possible to tear the flex pipe by simply flexing the engine. For those of you w/ MTX, ATX engines flex a lot more under load even if all is well and flexpipe about a foot long is there to compensate (my '96 was an ATX). It won't affect power directly, but it's not good to keep it that way.
3. The problems started after 4000 RPM drop. My knowledge about ATX internals is such that I am not comfortable to comment in this. I would say it's possible to f**k it up like that, but probably not after the first time.
OK. Now you will have to hear the rest. I just spent two days working on my car, I am a little tired and I am a little wired because not everything went as I planned. So bare w/ me. I just spent 30 minutes of my life researching the problem this kid has, I might have done something else, something more interesting to me. However I did that, partially because of this thread BS. I don't expect anybody in their right mind would do it for every person coming to this site and asking questions. Especially like the original. Now, I also supect that much like we didn't hear any sensible answer before, we won't hear comments to my post now. Besides, new cat (and labor, because psychojetpilot does not work on cars,as we learned) will tip off at above $200. There you go.
Now, as a general comment. If you are interested, you can go to the forum archives and look at the posts made by me there. Most of them are in troubleshooting section. And we are talking 1000+ here. Fortunately or unfortunately, I don't have enough time to do this anymore, but I trust that most of the same questions were asked and answered on the new board over and over again. All of them, and then some. All this informatiopn is available at a click of a button! People complain about search nazis, and what not, but let me also tell you this. I was working on my front suspension for two days. I had a problem and I ran a search in suspension forum. I found 5 separate threads w/ the same problem beaten to death, patiently answered or sometimes linked to the older answer. So why am I -- w/ over 5 years of CEG exposure -- doing the search never assuming my problem is not distinctly unique, and why other people who just came accross this site rush to ask questions?
. That always means alot 
Best bang for the buck.
