You guys think I'll gain anything by adding these to my car. I'm think that I may lose some low end torque. They look great, which is part of the reason I want them but I don't want to hurt my numbers. What do you think?
Will I gain anything with these?

You won't lose a thing.
Are they 1 5/8 FMS? I love the look of those. I've contemplated pulling my Macs and going FMS, simply because they look so much better. Well, that and the fact that my plug wire boots won't keep getting burnt...

They'll work even better if you run some free flowing mufflers along with a 2.5 inch (or bigger) exhaust setup. Your exhaust is usually only as good as the smallest orafice along the system.

1 5/8 FMS Headers
PJM99 - I put a set of those on my car at around 25,000 miles. At the same time I bumped the timing to 13 deg BTDC and removed the silencer. While I wouldn't say it made a big difference, the car did seem to run a little stronger. I think in order to really prove any benefit, you'd have to measure 1/4 mile time, compare against against another car (before and after), test with a G-Tech Pro, etc.
The installation was very 'straight forward'. Now at nearly 200,000 miles, the headers are still fine, although I haven't kept 'em as clean as I probably should have.
Best Regards,
Bob S.

One more real world "do it man" for the M9430-P51 ceramic coated FMS headers. Best shorty header on the market, subjectively speaking, of course. Love the continuous flange. Had the MAC's, the BBK headers, etc., none even compare to the build quality. And the look of those non coated headers after 5,000 miles -- pure unsightly. Remember, Ford placed a lifetime warranty on the M9430-P51 for a reason. That alone is proof of the quality.
Even emissions legal, too.
Again, subjectively speaking, the P51 header really doesn't begin to open up until 3,600 RPM (really starts to perform over 4,000 RPM) and pulls good until the shift point of 5,500 RPM, 6,000 RPM, 6,250 RPM, 6,500 RPM (whatever the upper limit of the shift point is).
