Its hard for me to believe, unless the xpipe was a HFC or no cat xpipe. However, even then for just a good 200cpi metallic cat or catless to gain that kind of hp? I would like to see an independent test by someone who took the plunge and do their own testing. Also, 32rwhp will show up on a timeslip. It would be interesting to see what is really gained on mph.

my guess is 32 RWHP @6800rpms and lost about 70 rwt throughout the band..
after all the claims ive been seeing aobut 20 hp(cai), 20 (tune/cams) there now 32?
wow so with bolt ons and tune we can have close to 2007 gt500 hp. i HIGHLY DOUBT IT. need to see some independant claims sorry i just dont belive that

There is a debate even if they help the GT500's. Some people posted not that much of a gain for the expense and the hassle of LT's. However, I am optimistic....just 32rwhp seems a tad high. Look forward to what others are going to get.

This tidbit of Tom@ARH's post makes me optimistic:
"Someone mentioned the gains are absurd. They're not. What's absurd is how powerful this engine truly is. As we've found, these engines are breathing through a straw. With headers, CAI's ...etc who knows where the power will end up. Hang in there for more information coming soon."

You probably already read this.
Guys, The headers were prototyped on an automatic. The clearances are quite good. Don't believe the hype. The factory manifolds are just a tad better than standard cast manifolds. It won't be long before our header systems are in your hands. You will see similar gains. We're anxious to see what various tuners around the country will get out of the system when combined with a good tune. That should be interesting.

I'm sure JJ will do whatever ARH claims needs to be done and test to see if that's true.

the gains were with headers, catted xpipe, and stock catback. seems about right to me.
look guys the stock headers are ONLY anti reversion. they are not equal length merged longtubes.
my bet is 15-20 rwhp from the headers and the rest from the high flow catted "X".
our CAT pipe is horrid. it could not be worse for power.

Yep for sure, they're definately hidden HP to be found with this engine. It's like it 's in a restrictor plate mode right now.
I'd love to see how much HP and TQ the 5.0 did when they shot this dyno pull.

Good to see such increase due to headers swap only over the already good factory ones.
I was reading one of Motor Trend issues and under the "secrets fo the 5.0" section, they highlighted how the factory headers were good compared to others.

tubular stainless headers to optimize breathing. Those headers are the work of Ford engineer Adam Christian, who fabricated them in his home workshop after supplier prototypes weren't generating desired results. Christian's manifolds bumped output by six horsepower and 14 pound-feet.
