The headers fit great, no issues. Visibly a lot larger then the skinny things that came off.
The car does feel slightly more torque then usual. Sound seems a bit more deeper.
Before installing the headers I had
evo air intake
fabspeed max flow exhaust
and GIAC chip

Did you take the time to clean up the X51 headers? The insides are pretty sloppy from the way they welded them up. I took the time to clean them up a lot before I put them on my 997S. Here's a before and after shot,--and the tools it takes to clean up the insides of these headers.

I just got my ECU flashed last night. The throttle response is much crisper and more engaging. I drove it like I stole it for 30 min to have the ECU adjust to the new fuel mapping. I did not pay retail on it and don't think its worth that much. However, it is a good mod at 50% of retail. I was talking to my tuner and he told me that if I upgrade headers, which is what I am thinking about doing, he will adjust the ECU mapping again to be even more aggressive with the timing given the new increased airflow.
You may want to see if you can go back to GIAC to have your mapping readjusted.
