I installed these, picked up 24 rwhp with the stock cat-back. The steering shaft seems to rub a little... going to bang it out whenever I get some free time.
It was a BITCH of an install for mine. Not sure why. Everyone else had easy times but mine was ridiculous... took 9 hours... but it did give me a reason to replace both engine mounts too, so that was nifty.
The headers seem to be great quality... the girlfriend got me the right present this year =P
Now at 372 rwhp... Next is cut-outs and our NSSP cam.

That is correct
324 rwhp untuned
335 tuned
348 fast 92/90 retuned
372 OBX headers retuned
I think I'm going to do cutouts of some sort before the cam. I need to take a better look at the underside to see if I can accomplish what I want, but basically I want to have a cutout that will bypass the mufflers when open... not just spew exhaust fumes under the car. Would be thrilled to see 380+ from this... considering that the mufflers seem restrictive I think that is possible!
As for my install, it was 8 hours of header install... which was very tedious. I'm sure it could be a little quicker now, but if someone offers to install it for $400 I'd take it LOL.

if it means anything, I had done a dyno run, change to a magnaflow muffler, and gained 1hp on my TA. I would agree with itsslow98.
The best I whacked out with the 92/90 fast combo, 160° stat, CAI and a Tune (nothing else) was 356rwhp and 333tq. - with a nicely lifted area from 5K on...
Bone stock as 324.4 hp / 318tq
I do all my runs 3x each and take the closest average run. Target 13.1:1 AFR (pre-cat)
Ref: to dyno compiled
348 is a hair low, but Im sure a bit o tweaking can bump it up.
Good to see an easy 25rwhp+ with these headers

Launching!
so question, I have a magnaflow cat back on my car and those cats look like they are slipjoint.....would they work with my catback if i cut the flanges and the flared lip? and maybe the cats would slide over my pipes?
