Questions about headers and bypass

If I'm laying out top dollar for new headers to pimp my ride, can anybody comment on the NHP headers with sport cats vs the Fabspeed headers with sport cats. They look pretty similar on paper/monitor. The FS unit comes at quite a price premium, does it have any special attributes to warrant this? Internet research hasn't been particularly helpful, other than to confirm the general good regard in which Fabspeed is held.
JD - I know you are quite the fan of the FS product, can you tell me why I should pay so much more for the FS headers as compared to NHP?
Anyone out there with experience, positive or negative, that might inform my decision?
Also, for people who have done this, how high is the likelihood of me shearing off a bolt at the header flange while removing the old headers? Is this job something I should pass off to a "real" mechanic who is prepared to drill and tap if necessary?
Thanks guys.

I have the NHPs on my 3.6 Box & they are fine for it. I own a pair of fabspeeds for a 987 & they are better quality & design, but my budget does not provide the extra $1300 for 5-10 HP. Less of a difference for a 3.2L engine. I believe you will be happy with either. As for the header bolts, soak overnite with good rust penatrant, then using a quality (Snap-On) 6 point socket loosen each bolt before removing any bolts. If any bolts resist coming loose retighten all bolts & take car to mechanic to remove stubborn bolts. After bolts are removed very easy job!
